You hyperventilate right before the take, the same technique as for swimming underwater [not highly recommended underwater, but in air, of course, you can change your mind and breathe again at any time]. Also, bear in mind, you're "dead" so not doing much in the way of running around getting out of breath.
Zombies would be a whole different question and ...
Unless they're performing in a play, actors don't generally memorize the entire script before the film starts shooting.
The reality is, the film will take (on average) 6-12 weeks (or more) to film and the script will likely change constantly. While it's certainly good for an actor to be very familiar with the script so they know what's going to happen, the ...
If you talk to actors that do a lot of CGI, the answer is "not very easily". (Ian McKellan famously almost quit filming The Hobbit because most of his work was acting solo, since they had to CGI in the hobbits later to make them short.)
However, there's a couple of techniques that pop up frequently in CGI-heavy movies:
The "tennis ball". Often an actual ...
It's only difficult to not look into the camera for you because you're not used to being around them. If someone's taking a photo or video of you, you're "trained" to look at the camera because it's generally a portrait-style shot.
Actors are trained to not look at the camera. Looking at the camera is called "spiking the camera" and it means that you've ...
I don't know the answer. But here's a potential candidate. Unlike the aforementioned films that involved digital cloning of one character (Clone Wars, The Matrix, Charlie and the Chocolate Factory), Buster Keaton physically acted out (from my count) 27 separate roles in his 1921 film The Play House
From State.com (emphasis mine):
Beth McGuire: Visually, that’s where we were. Linguistically, what we did is we honored the genealogy of the precursor to Black Panther—Captain America: Civil War. T’Challa’s father, T’Chaka, played by John Kani, is in the previous film. John Kani is from South Africa and he’s Xhosa, and he’s playing the king of Wakanda. So,...
Practise and familiarity.
The actors will already know the lines by heart. The first couple of blocking run-throughs, even before camera is set up, will let them get over most remaining giggles. You'd be amazed at how rapidly even a good gag can become just another line after repetition.
After that, if someone improvs something completely out of left-field, ...

Peter Dinklage is a vegetarian. He has been a meatless eater since the age of 16.
In all of the scenes that require him to be eating meat with his dear family in King’s Landing, Dinklage eats tofu or fake meats instead.

There's a wiki article on this too - List of characters played by multiple actors in the same film
The highest film I can find that definitely meets the requirement is:

At the point where Jonathan Harris joined the show, everyone else had already signed contracts that said where their names would be put on the billing, so he unfortunately would have to be last. As consolation, he negotiated to be listed as a "Special Guest Star" because it was "ridiculous", according to what he said at New Jersey's ...
I have also worked on film sets and I concur with @Nobby. I think a larger point, though, is that situations are generally only “scary” when actors are in character. For example consider Halloween. An adult dressed like a corpse and covered in bruise makeup and fake blood isn't scary to most children if she’s chatting and laughing and walking around as if ...
For example an actor does not like to go nude or shoot a sensual scene.But if it is a part of a script, can they choose to not do it? or do they HAVE to shoot because of the contract despite not having personal approval?
The choice is always the actor's.
The actor's contract will spell out what they are willing or unwilling to do. Some refuse different ...
In a movie, you typically don't need to learn the whole script. You just need the current scene, and that's usually just a few lines - easy to learn on the spot. Most of the practice is spent finding good ways to express yourself, I'd guess. And worst-case scenario, you just wasted a take - you can (almost) always just try again, and leave picking the best ...
Kind Hearts and Coronets is a full length film where Alec Guinness plays eight members of the D'Ascoyne family: Ethelred "the Duke", Lord Ascoyne "the Banker", Reverend Lord Henry "the Parson", General Lord Rufus "the General", Admiral Lord Horatio "the Admiral", Young Ascoyne, Young Henry and Lady Agatha D'Ascoyne. He also plays the seventh duke in brief ...
Apparently Keanu Reeves, after the Matrix experience, got hooked on Martial Arts. But as far as the movie is concerned, we're talking about choreography (you learn moves as when you do with dancing).
According to The Matrix FAQ on Imdb:
The actors that were hired had some kind of physical background; Carrie Anne-Moss was a dancer and Keanu Reeves used to ...
Depending on your definition of "Played" and "Movie", Doctor Who counts.
First is the "Doctor Who: The Curse of Fatal Death" comedy special, (a spoof of DW prior to the revival, really), we have 5 doctors in as many minutes:
Rowan Atkinson (The 9th Doctor)
Richard E. Grant (The Quite Handsome 10th Doctor)
Jim Broadbent (The Shy 11th Doctor)
Hugh Grant (The ...

Stefan Kramer as himself, and

"A-list" actors are exceptionally successful, their notoriety extends beyond the silver screen, and their name guarantees a box office hit.

There is at least one example of a prominent, A-list actor, Marlon Brando, who did not memorize his lines. Cue cards were printed with his lines and he would read from them.
This article discusses some of the tricks used in The Godfather:
His lines were printed and placed in his character’s line of sight; stills from the production show that they ...
Just to share one related example: Linda Blair in the Exorcist did not understand what she was doing when she was told to act out the masturbation scene. It was only years later that she figured it out. So it's quite possible that child actors are often not quite aware of the exact nature of the scene they're acting out.

Jonathan Harris did not join the cast of Lost in Space until after the show was already in production, not being in the pilot. At this point the billing had already been finalized, so through contract negotiations, he was able to be billed as a 'Special Guest Star' for every episode. According to him, starting the entire "Guest Star" billing in ...
Does the "Malkovich Malkovich" scene from Being John Malkovich count? It's difficult to count precisely how many Malkoviches are in this scene; I counted 45 while going through shot-by-shot, but I may have missed a few and/or double-counted some. These are obviously not named roles, so it may not count for what you're looking for.
It's a combination of Rami Malek's voice, that of Freddie Mercury, and of Marc Martel:
Even though Malek was singing, he still needed to lip-sync to Mercury's recordings, so they could overdub his voice where necessary.
Here's an article about the process.
