Why does Brad Pitt always seem to appear in movies where a person's name is involved in the title? Check out this chronological list of his work:
The Curious Case of Benjamin Button
The Assassination of Jesse James by the Coward Robert Ford
Mr. & Mrs. Smith
Meet Joe Black
Thelma & Louise
And that's just for feature films. I'm not even counting his voice work on Sinbad: Legend of the Seven Seas.
He must be turned on when he sees a script with a name in the title. I assume the twins were conceived the night he read The Assassination of Jesse James by the Coward Robert Crawford.
