What movie features a cast with the most actors who have won Oscars from other movies? (Sheesh, that’s one hard-working question.)
They have to have won as best actor / actress in either main or supporting roles (no wins for writing or directing) and they could have won the award either before or after the movie in question.
Best I could come with -which was on TV yesterday and which set the wheels in motion for this question- is Batman (the first one) which features three winners. There is Nicholson -who has won for several films, Jack Palance -best supporting actor from City Slickers and Kim Bassinger who won in L.A. Confidential.
There has to be a movie that features more than that though. Right?
