Actors and crew working on the new Harry Potter films are picking the set apart to find suitable souvenirs to take home once the movie franchise wraps up.Stars including Daniel Radcliffe Emma Watson and Rupert Grint , are close to finishing work on the last two films in the series - Harry Potter and the Deathly Hallows - which will be split into two movies.And as 10 years of work on the wizard films draws to a close, the actors have reportedly joined production staff in scouring the set for keepsakes.Production designer Stuart Craig , who has been working on the film series at the Leavesden Studios in Hertfordshire, England, says, "The Great Hall (featured in the movies) is a bit like the Berlin Wall - you can see people standing in line waiting to get bits of it."
