Robert Pattinson told Reuters he may be too old to play Edward Cullen again if Stephenie Meyer was to write a fifth "Twilight" book and it was made into a movie by Lionsgate's Summit Entertainment.

The 25-year-old Pattinson, talking at the Bel Ami premiere at the Berlin Film Festival, said: "I'd be curious what Stephenie would write, but I just think I'd probably be too old. I'm already too old. But yeah, it'd be kind of interesting."

The four "Twilight" movies have earned about $2.5 billion at the worldwide box office already, with The Twilight Saga: Breaking Dawn - Part 2 hitting theaters on November 16.
