Though this may be a duplicate of Why are some actors uncredited in certain films? I felt it worth adding this point, that some people may not be aware of.
Her IMDB page credits her as "Policewoman" - no character name.
This is a classic sign that someone is adding their own IMDB credits as an "actor" when in fact all they were was a Supporting Artist... an Extra.
There are some extras doing this to such an extent that it actually boosts their popularity rating on the StarMeter above that of some genuinely famous actors.
A busy extra can work on 100 shows/movies a year.
A good jobbing actor/day player maybe 20.
A Hollywood A-Lister perhaps only 2.
This allows extras to 'game' the system & artificially push their popularity higher... a practise I personally find despicable.
If they walk past in the background in 4 Hollywood blockbusters in a year - so far back even their grandmother wouldn't recognise them in it - then self-accreditation gives them the same amount of 'popularity' as the A-List actor who spent 2 months in front of the camera doing all the actual acting.
I got two lines in a movie I worked on last week, as "Local#1" - scripted dialog which actually entitles me to a credit, (rather than the 1st AD saying, 'could one of you shout "Hey You!"' - which wouldn't).
Will I be putting that on my IMDB page?
I will not.
