Mickey Rourke — Joe Eszterhas Is Just Bitter Mel Gibson Didn’t Like His Script

Mickey Rourke continues to be Team Gibson all the way in the Joe Eszterhas/Mel Gibson feud — telling our photog that Joe is just upset that Mel didn”t want to make a movie with him.

Rourke — who would only talk to us for a second straight day if our camera guy bought him ice cream — said that Eszterhas is just bringing up “old s**t” because he has a personal beef with Mel.

Rourke supports Mel even though he knows it”s not the popular thing, telling us, “I know my agent is going to yell at me tomorrow for sticking up for Mel, but … somebody has to.”
