After he interrupted Ben Affleck’s speech at the SAG Awards on Sunday night to yell “Happy MLK!” from the stage, Cuba Gooding Jr.’s unpredictable behavior kept going.

During a Weinstein Co./Netflix after-party at the swank Sunset Tower, Gooding took a break to run across Sunset Boulevard, stopping traffic on the way, so he could ride a mechanical bull at Western-themed bar Saddle Ranch.

Back at the after-party, guests including Julia Roberts, Mariah Carey, Steve Coogan, Michael Douglas, Kerry Washington, Daniel Craig, Kevin Spacey, Sacha Baron Cohen, Ewan McGregor and Philomena Lee hung by the pool, while Lupita Nyong’o, Jared Leto and Anna Chlumsky led the dancing.
