People who have car collections - I never understood that. I always thought that was unnecessary. It's not beautiful, it's not creative. It's just showing how much money you've got.

In a 2005 interview Radcliffe singled out the humour as being a reason for the movie's creative success. Writing short stories and poetry is also a passion. Both the actor and production received favourable reviews with USA Today commenting: "Radcliffe ultimately succeeds not by overshadowing his fellow cast members but by working in conscientious harmony with them – and having a blast in the process.

He will play beat poet Allen Ginsberg in the 2013 indie film Kill Your Darlings. Radcliffe has contributed to many charities including Demelza House Children's Hospice and The Trevor Project. He also began to branch out to stage acting in 2007 starring in the London and New York productions of the play Equus and in the 2011 Broadway revival of the musical How to Succeed in Business Without Really Trying.
