Daniel Radcliffe Kissed Paul Dano & Paul Dano's GF

At Sundance Film Festival 2016, Paul Dano and Daniel Radcliffe came together for the world premiere of Swiss Army Man, the absolutely bonkers directorial debut from The Daniels, Daniel Kwan and Daniel Scheinert. The film's IMDB synopsis for the film reads, "A man in the wilderness befriends an unlikely counterpart." But in actuality, the one sentence description is quite tame. The story centers around Hank (Dano), a young man who runs away from home and becomes lost in the wilderness. As he is about to commit suicide, he sees a dead body named Manny (Radcliffe) wash up on shore. He befriends the dead body, and drags it along with him as the two attempt to find their way home. Needless to say, it's an absolutely ludicrous film, yet someone Dano and Radcliffe completely pull it off.

The film is very much a two-hander, with a few additional characters coming in in the third act, so most scenes focus on Hank and his rotting corpse of a friend, Manny. Through their journey, the unlikely pair become very close. Radcliffe, who fans know from the Harry Potter series, and Dano, who has appeared in such films as 12 Years A Slave, Prisoners, and There Will Be Blood, have an unusual connection to one another. They've both kissed each other's girlfriends, and now, each other.

Dano has been dating Zoe Kazan, who Radcliffe starred opposite in 2013's romantic comedy What If, since 2007. And Radcliffe's girlfriend is Erin Darke, who played the wife of Dano's Love & Mercy character in 2014. And with Swiss Army Man, Dano and Radcliffe have also shared an on screen kiss. After the premiere screening, Dano divulged: "We'd met before but this was a much more intimate experience," he says of his relationship with Radcliffe.

"We'd met a couple times over the years at various things. There's this strange triangle now where I worked with Zoe in What If and Erin worked with Paul in Love & Mercy, and now we've kissed" he says, motioning to his Swiss Army Man costar. "So it's just very incestuous."

It seems the only way it could become more "incestuous," as Radcliffe calls it, is if Kazan and Darke also shared an on screen kiss.

Well, there's always Sundance 2017.
