Jennifer Garner hides from fans while attending 'Peppermint' screening

Jennifer Garner seemed to be embarrassed about going out to watch her own movie.

Garner documented her time at a Los Angeles movie theater, where she attended a showing of her new film “Peppermint” as a regular viewer. But she hardly enjoyed herself — she admitted she was worried the audience would “hate the movie” and think she was “obsessed” with herself.

“I’ve never done this before, and now I know why,” Garner said in a video posted on Instagram on Monday. “Hi. I’m in a movie theater and I have a movie out and I have to be here with my fans.”

“I’m afraid people are gonna hate the movie and take pity on me, see me and think I’m just obsessed with myself. Nonetheless, I have tickets,” she added before hiding her face in her sweatshirt.

The actress walked through the theater with embarrassment and whispered, “Is it over?” before running into a dark corner. Despite her worries, a fan approached Garner and said “Peppermint” was “amazing.”

“The studio encouraged me to go to the theater and see #PEPPERMINTmovie with an audience — maybe they thought I would conduct exit polls? But I learned something about myself on this experiment — I am a chicken,” the actress said. “Thank you to everyone who spent their weekend and their hard earned money with #RileyNorth and me. If you go this week — you never know — I may be lurking behind a curtain at a theater near you.”

In "Peppermint," Garner plays Riley North, a mother-turned-assassin seeking justice after a drug cartel killed her husband and daughter.
