Zac Efron & 'Baywatch' Cast Film Night Scenes on Boat

Zac Efron takes a look around on set while preparing to film a scene for Baywatch on Wednesday night (May 4) in Tybee, Ga.

The 28-year-old actor was joined at the night shoot by his co-stars Kelly Rohrbach and Alexandra Daddario.

Kelly was dressed in a glamorous look from the waist up, most likely shooting close-ups. Alexandra was spotted sitting alone on the doc while checking her phone between takes.

Two nights earlier, Zac had been spotted out hanging out with some friends at one of the local bars in town.
