Zac Efron jumped into the saddle to ride a horse on the set of Neighbors 2: Sorority Rising in Los Angeles Wednesday night

Zac Efron Films ‘Neighbors 2’

Efron hopped up on the horse and started waving a fraternity flag in the scene that was being filmed. In addition to the Kappa Nu flag, Efron was repping his character’s frat with a t-shirt emblazoned with its Greek symbols. Joining Efron on the Neighbors 2 set Wednesday was costar Chloe Grace Moretz, who donned a wig and tight mini skirt for the shoot.

Throughout the filming of Neighbors 2, Efron has been posting pictures from the set. In one Instagram snap, the actor is posing on top of a muscle car as a football tailgate rages on in the background.
