CLEVELAND -- There was a lot of action outside the 9 building in downtown Cleveland overnight.

Crews were busy filming scenes for the upcoming Matthew McConaughey movie White Boy Rick.

A portion of E. 9th Street was temporarily closed as a result.

The film is based on the true story of Richard Wershe Junior who became the FBI’s youngest informant ever at age 14 before becoming a drug dealer.

McConaughey plays the boy's father.

The film -- which also stars Jennifer Jason Leigh, Bruce Dern and Piper Laurie -- is set to hit theaters early next year.

White Boy Rick has been filming throughout the Cleveland area for weeks now.
