The actor, who plays werewolf Jacob Black, told MTV News that he preferred Eclipse's more adventurous tone.
"It's my favourite, because it's the most guy-friendly by far," he explained.
"It's dangerous. There's a lot of action. The romance is still there, but the action level is stepped up way more. It's great."
He added that he felt pressured to make the film as good as possible.
"It was my favourite book, so I was always looking forward to the day that I got to film it. The final product turned out even better than I expected."
Twilight: Eclipse opens on June 30.
