Jamie Bell is inspired by Andy Serkis.

The 29-year-old actor used motion capture to portray The Thing in 'Fantastic Four' and learned a lot about the technique from his 'Tintin' co-star, who most famously used it in 'Lord of the Rings' and 'King Kong'.

Jamie said: ''I've worked with Andy Serkis a few times now, and seeing how he creates those characters is inspiring.

''When I did 'Tintin' I was asking a lot of questions.

''It's all about breaking through that wall of technology and getting through to people. You need to work closely with the visual effects people to make sure you have authorship of your performance.

''That can be blurry at times, but as long as you're in close contact, then you're fine.''

Jamie also had his voice digitally altered because he and film bosses felt it would be ''pretty silly'' for him to change his tones himself.

He explained to Shortlist magazine: ''We had a few conversations and we ultimately decided it would be pretty silly for me to put on a voice.

''You lose a sense of who the character was before. They've changed my voice in post-production - it's me but slightly warped.''
