Kellan Lutz claims the 'Twilight Saga' movies were not a "well-oiled machine".

The actor - who plays Emmett Cullen in the vampire series - admits he feels "blessed" to have taken part in the franchise, but found new movie 'Immortals' "much more enjoyable" because of the atmosphere on set.

He said: "'Twilight' is kind of crazy. I'm very happy to be a part of them. But the last movie took seven months, and still wasn't a well-oiled machine and it gets kind of tough.

"We're all very blessed and I love the experience. But working with Relativity and doing 'Immortals' was just a world of difference, so much more enjoyable."

Kellan added he particularly enjoyed getting to know his co-stars, including Henry Cavill and Mickey Rourke, on the fantasy action film.

He added to The Hollywood Reporter: "Everyone just treated everyone like they were family. It's just a really great experience to enjoy feeling like an equal on the set and it's not a machine, it's a family."

Freida Pinto, Luke Evans and Stephen Dorff also star in the Tarsem Singh-directed film.
