In a new interview with Steffan Rhodhi, who will be playing Reg Cattermole in Deathly Hallows, the actor discusses when he will be filming for the movie.

Then he will move into a London studio to film his scenes for Harry Potter And The Deathly Hallows: Part I. His character is from the Magical Maintenance Department and his identity is borrowed by Ron Weasley.
Steffan, who has a role in the new Harry Potter movie which he begins filming next month, is now best known for playing Dave – even though his agent advised him against the role.

“My agent said ‘you can’t just keep doing every small part – they will think of you as a bit-part actor.’
Steffan is playing Reg Cattermole in the new Harry Potter film and he thinks his two teenage children are “secretly chuffed” with his new role.

“I think they are a bit fed up now of friends coming up to them and going, ‘What’s occurrin’” he laughs, referring to Dave Coaches’ catchphrase.

Thanks SS!
