Pretty Little Liars stars share their favorite Harry Potter moments

To celebrate Harry Potter’s birthday, Freeform is throwing a party — and by that, we mean they’re launching a three-day Harry Potter marathon.

Starting on Friday, July 29, fans will be able to watch the documentary Tom Felton Meets Superfans on the Freeform app. The project shows Felton’s interactions with some of the phenomenon’s biggest fans, along with his conversations with his co-stars.

Furthermore, at 3 p.m. ET on Friday, Freeform will begin its marathon, airing the first two Harry Potter films, with three more on Saturday, and the final two airing Sunday.

To kick off the fun, EW has an exclusive video in which Freeform stars share their favorite Harry Potter moments. Yes, even the Pretty Little Liars are superfans.
