Phineas and Ferb” know what they’re going to do this summer: The animated Disney series’ next film, “Phineas and Ferb The Movie: Candace Against the Universe,” will premiere August 28 on Disney Plus.

Executive-produced by “Phineas and Ferb” creators/executive producers Dan Povenmire and Jeff “Swampy” Marsh, “Phineas and Ferb The Movie: Candace Against the Universe” centers on Phineas and Ferb’s older sister Candace (voiced by Ashley Tisdale), who feels underappreciated by her family and then is abducted by aliens — who seem to worship her. But they’re obviously not what they seem.

Besides Tisdale, returning voice talent include Vincent Martella as Phineas Flynn; Caroline Rhea as their mom, Linda; Dee
Bradley Baker as Perry the Platypus; Alyson Stoner as Isabella; Maulik Pancholy as Baljeet; Bobby Gaylor as Buford; Olivia Olson as Vanessa Doofenshmirtz; Tyler Mann as Carl; and Povenmire and Marsh as Dr. Heinz Doofenshmirtz and Major Monogram, respectively. David Errigo Jr. joins the cast as Ferb Fletcher.
