Ali Wong stopped by Jimmy Kimmel Live [1] on Tuesday to discuss her career, including the success of her recent Netflix film, Always Be My Maybe [2]. During the chat, she talked about working with Keanu Reeves [3], who makes a memorable appearance [4] in the romantic comedy. She revealed that Keanu surprised her in May by showing up to the film's Los Angeles premiere. "He hadn't seen any footage of the movie, so we didn't know how he was going to react," Ali said. "And he happened to be sitting right behind me during the movie." Thankfully, Keanu had a very positive reaction to the film [5] — so positive that he kept belly laughing throughout the screening. But apparently, Keanu has a very unusual laugh, which Ali revealed by mimicking the somewhat diabolical but highly entertaining howl. Watch her "HA, HA, HAAA" her way through the impersonation at the 7:38 mark!
