HOW I WON THE WAR (1967) 1/2* The thing about making surrealistic films with nonexistent or scant nonlinear plots is that it's good to provide something else of value or interest. This doesn't. In his only dramatic cinematic role John Lennon demonstrates that he's good for sudden bursts of unbridled energy (Yoko-like) but gives no evidence that he's gifted in acting, as he was in so many other artistic endeavors.
