For Potterheads, choosing a favorite Harry Potter movie kind of feels like picking a favorite child: you say you can't play favorites, but deep down you do. Franchise star Daniel Radcliffe, a.k.a. Harry Potter himself, is no exception. In a recent interview with WIRED, the actor—whose new TBS series Miracle Workers premieres this week—revealed his favorite film in the franchise … and it just may surprise you.

"I love the last one [Harry Potter and the Deathly Hallows - Part 2], but I also really love the fifth [film, Harry Potter and the Order of the Phoenix], which is not a lot of people's favorite," the 29-year-old said. "I love it because of the relationship between Harry and Sirius Black."

In addition to explaining that part of his partiality toward Harry Potter and the Order of the Phoenix is that "you get a lot of Gary Oldman in that movie," (Oldman portrayed Sirius Black, Harry's godfather), Radcliffe also said that it was the most enjoyable filming experience. "That was my favorite one. Probably to film as well. We had a really, really good time making that one. Five or seven, part two," the actor added.

Radcliffe is not alone; no true Harry Potter fan would find it easy to narrow the series down to just one film.
