Lions Gate Entertainment Corp. said Monday it has signed a multiyear deal to distribute Relativity Media productions in the United States.

The Santa Monica company’s Lionsgate studio said it will acquire distribution rights for up to five productions per year as part of the deal with Relativity Media, based in West Hollywood and run by financier Ryan Kavanaugh. Financial terms were not disclosed.

The first title to be released under the new pact is “Brothers,” directed by Jim Sheridan and starring Tobey Maguire, Jake Gyllenhaal and Natalie Portman. The companies earlier partnered on movies that include “3:10 to Yuma” and “The Forbidden Kingdom.”

“Ryan Kavanaugh and his colleagues at Relativity Media have built an extraordinary company that is one of the industry’s most prolific suppliers of broad-appeal, talent-driven motion pictures,” said Joe Drake, Lionsgate president, in a statement. “This agreement solidifies the long-term relationship we built together through successful partnerships” on past films.

Lions Gate shares closed down 12 cents, or 2.4 percent, to $4.84 on the New York Stock Exchange.
