A german documentary about a war game in Russia. Watch it until the end, it's worth it. The version with english subtitles was the best I could find.
For years, there was a rumor of practical joke recorded during the shooting of Indiana Jones and the Temple of Doom. Specifically, Instead of Indy being whipped by a Thuggee slave-driver, Barbara Streisand came in, wearing a dominatrix outfit, and starts lashing Indy with his own whip. Then Carrie Fisher jumped to Indy's defense, and director Irving Kershner criticized Steven Spielberg's directing of the scene. Well, it's not just a rumor (YT 1:25, with transcript).
