Keanu Reeves on having sex with the director's wife in his latest movie

It must be hard enough filming an explicit movie sex scene in front of anyone, but imagine having your screen partner's spouse on set because he's the director.

That happened to Keanu Reeves, 51, while filming his latest movie Knock Knock, an erotic thriller in which he co-stars with Lorenza Izzo, 26. She's also the wife of Eli Roth, 43, who directed the film. No pressure there.

Watch the Speed action star relive the awkward experience with Jimmy Kimmel in the clip above.

Now there's some seriously frightening on-the-job stuff. It kind of makes defusing bombs rigged in speeding locomotives look like a picnic in the park.
