Just days after the first red band trailer debuted for Warner Bros.' The Nice Guys, the studio released a new TV spot during this past week's episode of NBC's Saturday Night Live. Russell Crowe and Ryan Gosling star as a hired leg-breaker and a private investigator who team up to solve an L.A. mystery. Director Shane Black follows up his 2013 superhero adventure Iron Man 3 with this comedy, set for release on May 20, 2016.

The Nice Guys takes place in 1970s Los Angeles, when down-on-his-luck private eye Holland March (Ryan Gosling) and hired leg-breaker Jackson Healy (Russell Crowe) must work together to solve the case of a missing girl and the seemingly unrelated death of a porn star. During their investigation, they uncover a shocking conspiracy that reaches up to the highest circles of power. The supporting cast includes Kim Basinger, Beau Knapp, Keith David, Matthew Bomer and Margaret Qualley.

Shane Black directs from an original screenplay he wrote with Anthony Bagarozzi. Joel Silver is producing under his Silver Pictures banner, with Ken Kao of Waypoint Entertainment, Hal Sadoff, and Michael Malone serving as executive producers. Here's what director Shane Black had to say to People earlier this week about his R-rated comedy.

"It is an R-rated film and it's a caper. It's a little fast, a little funny and a little rough in places, kind of coarse. These guys are working-class dudes, they're not really sophisticated private detectives, so it's a chance to do the kind of thriller I don't see too much of anymore."

Both Russell Crowe and Ryan Gosling are no stranger to Los Angeles period pieces. Russell Crowe played a 1950s L.A.P.D. cop in the 1998 classic L.A. Confidential, while Ryan Gosling played a 1940s L.A. police officer in 2013's Gangster Squad. Take a look at the new TV spot for The Nice Guys below, and stay tuned for more on this R-rated comedy.
