Maybe it's the drunken midnight karaoke on Saturdays, or the slinky femmes fatales gyrating to James Bond theme songs, or some fat fuck in a red suit squaring off with green Martians, or Stalag 17or A Few Good Men, or the unashamedly fan's-eye musical homage to Elvis, The King.Or maybe it's all of them. But the Maverick Theater in downtown Fullerton is the most un-theater theater in the county, trafficking in film and multimedia as much as Shakespeare and Neil Simon. Founder Brian Newell has opened up his two spaces?including his 1920s-speakeasy venue?to everyone and everything, from committed thespians and iconic light and set designers (hello, Jim Book!) to standup comedians and even the Fullerton Music Festival in September. If theaters want to remain relevant in an age of iPhones and high-def this and that, more should look at the model Newell and co. are building.
