Everybody knows you never go full retard! Kirk Lazarus (Robert Downey Jr) is the Aussie Method actor par excellence in blackface giving retrospective advice to Tugg Speedman (Ben Stiller) the ludicrously vain Hollywood star who made that very mistake in his quest for Oscar. Now they’re in the jungles of Vietnam doing their version of the War years after everyone else has stopped those kinds of movies and causing no end of difficulties for hapless Brit director (Steve Coogan) who is killed in the fray. Back at the studio the vile boss Les Grossman (an unrecognisable Tom Cruise) just sees insurance $$$$ when Speedman gets separated from the crew as they go shooting guerilla style in a self-defeating move – and he’s kidnapped by drugs lords who make him act out Stupid Jack, the only film they have on VHS. Only Tugg’s agent (Matthew McConaughey) cares about his charge. The other actors, who include Fatties franchise star Jeff Portnoy (Jack Black) decide to rescue Tugg without realising their director is dead and this is not a movie any more … This is a Hollywood satire that also operates as a proper action movie and what a rare feat that is. Just when you think it’s a sketch show that goes on too long, Tugg kills a panda (he’s crusading for their rights on the back of Vanity Fair) and Danny McBride calls Nick Nolte ‘the Milli Vanilli of patriots.’ Gut-bustingly funny when it works, and you know all the movies it’s spoofing, Grossman was apparently all Cruise’s idea and some might say it’s a rather vicious take on Sumner Redstone as revenge for booting him off the Paramount lot when he jumped on Oprah’s couch. From a story by Justin Theroux and Ben Stiller, written by Etan Cohen. Directing by Ben Stiller. Dancing by Les Grossman!
