Daniel Cudmore (Felix) gets asked by Glamour UK about having time to hang out with the Twilight gang during or after filming:
A: Um, not so much Taylor. Rob and Kristen a little bit, here and there. During filming they were always working. So, a little bit off camera, but not a lot.
He also mentions that the scene most people talk about from the Twilight saga with him in it would be in New Moon where he fights Edward:
A: I think so, just because it was the first experience with the character and also the fact the lead character is almost being killed, um, a lot of fans weren’t too happy with me, which in turn I was thrilled about because it means I did my job properly.
