Potterheads rejoice: Starting Thursday, all of the Harry Potter films are showing in Imax theaters across the country — including, for the first time, “Sorcerer’s Stone” and “Chamber of Secrets.” That troll in the dungeon and slithering basilisk snake will have never looked so big.

The one-week film festival is part of the buildup to the newest Potter film, “Fantastic Beasts and Where to Find Them,” which stars Eddie Redmayne as the magical-animal expert Newt Scamander. (Watch the movie’s latest trailer here.) “Fantastic Beasts” premieres November 18 and is directed by David Yates, who made “Order of the Phoenix” and all of the Potter movies that followed.

Each of the Imax screenings will include a sneak peek of the new film.

You can buy single tickets to each screening, a day pass to see three or more of the films in a single day, four-show tickets or even a special festival pass, which will let you see as many of the films as you want throughout the week.

Imax has information on screening times and locations here.

If you live in the Washington area, you’ll probably be heading to the AMC Loews Georgetown in Washington; AMC Hoffman Center in Alexandria, Virginia; or Regal Majestic in Silver Spring, Maryland.
