In the upcoming thriller In Time, Justin Timberlake and Amanda Seyfried stop aging in their mid-20s — but that doesn’t mean the young actors are determined to stay youthful.
“I’m perfectly fine with aging,” Timberlake told PEOPLE during an event at the SLS hotel in Beverly Hills on Sunday. “I look back — as a lot of my younger years have been documented — and I can honestly say I would not like to revisit … a couple of outfits that I wore in ’99.”
For Seyfried, playing a perpetual 20-something may have actually aged her. “It was kind of an unhealthy thing to be doing every day for two months,” Seyfried told reporters of spending much of the film running at full speed in high heels.
But Seyfried had a Hollywood secret weapon: stunt heels. “I had many pairs,” she explained. “They are half the size of the original design.”
Seyfried added that remaining in the heels was also important to her character, for whom time is of the utmost importance. “It wasn’t like [my character] had time to take the heels off,” she said.
Director Andrew Niccol agreed. “She would also have been shot by the guy chasing her,” he joked.
In Time hits theaters Oct. 28.
