The following plot synopsis is for real, and not an April Fool’s joke: In the film Nine Lives, Kevin Spacey plays a workaholic businessman who learns a valuable lesson about love, life, and family when he transforms into the household pet cat. Ordinarily, The Dissolve’s NewsForce 5 wouldn’t feel the need to clarify that this film’s logline isn’t a put-on, but today is April Fool’s Day, and a slight variation on that exact scenario was joked about on 30 Rock. Beyond that, cats with the ability to talk are very funny. Nine Lives is all too real, and if you still don’t believe us, good ol’ Kate Erbland reported on the film back in January and News Commandante Rachel Handler remarked on Spacey’s casting in her Newsies.

Today brings another exciting development in this transcendently goofy-sounding project: Deadline reports that Christopher Walken has joined the Nine Lives cast, bringing the classic Walken X-factor to the film. He’ll play a role that also sounds like it’s part of a joke, but isn’t, as the owner of a “mystical pet shop, who assists [Spacey] during his time of feline stress.” If Deadline is having a laugh at the public’s expense, for shame, because that sounds gloriously silly. What makes this pet shop so mystical? Is it because businessmen trapped in animal bodies naturally gravitate there like salmon upstream? Is it because it’s owned by Christopher Walken? Will he wear a wig? How bad will his wig be? If this good-time family comedy ends with a musical number, will Christopher Walken dance? God, I hope so.

Nine Lives will be the latest feature from Barry Sonnenfeld, who last entered theaters with 2012’s better-than-average Men in Black III. The man’s filmography is distinctly uneven, balanced nearly 50/50 between quality (The Addams Family, Get Shorty) and less-than (RV, Wild Wild West). As such, there’s no guessing where Nine Lives will fall. But if general cat behavior—and the film’s incredible, ludicrous plot summary—are any indication, the film will land on its feet.
