Producers HARVEY and Bob Weinstein dismissed Depp as "too weird", but modest Damon believes the brothers must be secretly kicking themselves after seeing Depp's recent resurgence of success.
He says, "I was like, 'You've got to be kidding me. How is this part still available? Why isn't Johnny Depp doing this movie?'
"I found out the studio (Miramax) didn't want Depp at the time because they thought he was too weird and didn't have enough box-office clout!
"Of course, halfway through the production of Grimm, the Weinsteins watched Pirates Of The Caribbean explode in the theatres and they probably started screaming: 'Why the hell do we have Damon instead of Depp doing this movie?"
