It was
previously highlighted in an interview with
The Herald, that
Robbie Coltrane (Hagrid) did not know if he would be returning for '
Order of the Phoenix'.
In a new interview with
The Sunday Times he explains that he's finished the Potter films that he signed up for.
“Well, it takes nine months to make a Potter movie,” Robbie says. “There’s not a lot else you can do. You can’t tell people to put their film on hold till you’re ready in September, it doesn’t work that way.
“I mean, I’m doing this play but that’s only three weeks. We’ll see what happens now that I’ve finished the Potter films. I signed for four and I’ve done them now. There’s no great mystery to these things.”
What does this mean?
Basically, that Robbie, like most of the other adult actors, signed four-film contracts.
He has not stated whether he is or isn't doing OotP.
He's just saying that he's fulfilled his current commitment.
