Andrew Garfield 'very impressive' on Spider-Man set

Andrew Garfield is doing a "very impressive" job on the set of 'The Amazing Spider-man'.

Martin Sheen - who plays the titular character's uncle in the movie - believes the British actor is doing a great job as the web-slinging hero in the forthcoming sequel and reveals he has not "slacked" at all.

He said: "I went through a couple of very emotional scenes and he was right there, focused.

"And he was the same off camera, he didn't slack off. No sir, he was equally emotional off camera. Very impressive. He's going to be a huge star.

"He is quite the marvel, a very fine actor. He's a lovely guy, very disciplined, very focused."

'The West Wing' star Martin also revealed Andrew is a big fan of working with errors on-set and is working out regularly to keep in shape for the movie.

He told Total Film magazine: "He works in a very organic way - he loves accidents, when something happens in the scene that causes him to do something else.

"He's very athletic, he's in great shape. He plays basketball and he works out every day."

'The Amazing Spider-Man' is set to hit cinemas in 2012.
