M.i.'s Westside Comedy Theater sits in the alley between the Third Street Promenade and Fourth Street in Santa Monica. It opened in 2005 as the Westside Comedy Theater and took on the "M.i." portion in 2007 when they joined with Mission IMPROVable. Since the grand relaunch in 2009, this 2,000-square-foot performance space has offered a number of services for performers and filmmakers, including film shoots, seminars, casting calls and more. Improv troupes and comedy shows regularly take place on the stage at night. It also offers classes in improvisation, screenwriting and standup comedy. The space is available for rental seven days a week.
