Warner Bros has released a few new behind-the-scenes looks at the making of Harry Potter and the Sorcerer's Stone and Chamber of Secrets. Included in the previews are interviews with Daniel Radcliffe, Rupert Grint, and Emma Watson from not only the sets of the first two films, but Deathly Hallows; producers David Heyman and Mark Radcliffe, along with Chris Columbus explain how the films came together, from initial casting to editing scenes for the features. They can be viewed below.

The first video has a bit of a treat, where Emma Watson, from the set of Deathly Hallows, reads Hermione Granger's introduction in Philosopher's Stone.
