Now we all know the great Stan Lee is no more. I am wondering if he has already finished cameos for future Marvel or other movies.
According to inverse.com, he might appear in 6 unreleased films:
Ralph Breaks the Internet: It’s unclear whether or not Lee actually lends his voice to Ralph Breaks the Internet, but outlets are labeling it as a cameo, so Lee probably has at least one line.
Madness in the Method: Lee’s credited as “Stan,” which probably means he plays himself, a continuation of his iconic role in Mallrats (1995). Madness in the Method has no confirmed release date, having been seemingly stuck in post-production for quite some time now, but it’s expected by the end of 2018, according to IMDb
Captain Marvel: There’s no real confirmation just yet about whether or not Stan Lee filmed a cameo for Captain Marvel, but considering he definitely has one in Avengers 4 and Captain Marvel comes out before that, it seems likely. Production on the two movies overlapped somewhat, so it stands to reason Lee might’ve filmed a cameo alongside Carol Danvers around the same time he did for Avengers 4.
Avengers 4: Stan Lee will definitely appear in Avengers 4 in some fashion. Director Joe Russo has confirmed that Lee filmed his cameo for Ant-Man and the Wasp at the same time he did for Avengers 4.
Spider-Man: Far From Home: Much like with Captain Marvel, Stan Lee is expected to have some kind of cameo in Spider-Man: Far From Home. Especially because he typically filmed his cameos in batches, it’s possible that he filmed the Far From Home cameo around the same time he filmed one for Venom — both films were produced by Sony Pictures.
They added Dark Phoenix in the list too but EW confirms Stan Lee does not have a cameo in the next X-Men film Dark Phoenix.
And express.co.uk confirm his cameo for Spider-Man: Into the Spider-Verse, Captain Marvel and Avengers 4.
