ABC's classic hour-long dramedy Desperate Housewives was almost called The Secret Lives of Housewives. Jack and Karen's characters on Will & Grace were originally not supposed to be friends at all, but producers noticed Sean Hayes and Megan Mullally's chemistry. Sylvester Stallone asked Dolph Lundgren to actually punch him while filming Rocky IV. This left him Stallone in intensive care for four days. For his Oscar-winning role in The Revenant, Leonardo DiCaprio ate a raw bison liver, learned how to use a musket, learned how to build a fire, and studied two Native American languages. Paul Bettany, who plays J.A.R.V.I.S. in Iron Man, has never seen Iron Man. While filming a scene for The Mummy in which his character was hanged, Brendan Fraser actually lost consciousness and had to be resuscitated.
