'Nocturnal Animals' Costars Amy Adams and Isla Fisher Share Epic Tales of Being Confused for One Another

In what is easily the year’s biggest casting triumphs, Isla Fisher plays the literary avatar of Amy Adams in the new story-within-a-story thriller Nocturnal Animals. The red-headed actresses have long been considered celebrity doppelgangers, and yes they do get mistaken for one another in person, too.

“It happens “a lot,” Adams, 42, told us at the film’s recent Los Angeles press day. “We’re dispelling the myth that we’re the same person,” said Fisher, 40. “There are going to be a lot of surprised folks out there. Because I get congratulated a lot on Enchanted.”

Fisher has also received props for Adams’s achievements from one very famous pop star. “After the Oscars the year [Adams was nominated for] American Hustle, I’m talking to Bono,” Fisher recalled, then stopped to apologize for the U2 name-drop. “The crowds part and in walks Lady Gaga. And she goes, ‘I just want to say, you were wonderful in American Hustle.’ But I don’t want to correct her because Bono’s there. So I just say, ‘Thank you.‘”

The actresses’ resemblance has made for some good gags, too. Adams recalled attending Fisher’s birthday party, where the guest of honor’s famous husband, Sacha Baron Cohen, brought it up in a toast. “He’s [saying], ‘I wanted to date Amy Adams, but she wasn’t available,'” Adams said. “I felt really awkward.”

The Hollywood couple even had Adams’s head Photoshopped onto Fisher’s body for one of their recent holiday cards. “It’s a running joke inside their family,” Adams explained. “It’s said, ‘Season’s Greetings from Amy, Sasha, and the kids,'” Fisher revealed. “But what’s amazing is several people didn’t even notice it wasn’t me. Or that my name was written ‘Amy.'”
