The 'Harry Potter' television series has gone into production, with more casting news and photos set to be released over the coming weeks.

This is the first time, however, we're seeing the actors in their Hogwarts garb. Below, see the cast of "Harry Potter" side-by-side with the actors from the original movie series, which started in 2001 and concluded in 2011.

HBO Max's upcoming reboot of the Harry Potter series went into production in the UK earlier this week. Warner Bros. Studios is setting up a school for the young cast, including the three leads, so that they don't fall behind on their studies while filming.
