On Saturday morning, the Regency Theater and Bruin Theater in Westwood closed to host the premiere of “The Lego Movie,” a film about Emmet, an average minifigure who discovers he may be the Special, destined to save the world. In attendance were the film’s voice actors, an ensemble cast of comedy actors and renowned celebrities, including Chris Pratt, Cobie Smulders, Alison Brie and Will Ferrell. Stars brought their children along to the family-friendly occasion, along with the brick-themed after party in Bricksburg, a decorative town quickly built on the red carpet during the film’s screening. “The Lego Movie” releases in theaters nationwide on Friday, Feb. 7.
