What can go wrong does go wrong on OPENING NIGHT - not to be confused with the wonderful Cassavetes film - as stage manager/former actor Nick (Topher Grace, SPIDERMAN) deals with actor egos and insecurities, technical mishaps, accidents, and a vitriolic producer (Rob Riggle, THE HANGOVER) on the opening night of "ONE HIT WONDERLAND" starring J.C. Chasez (the "other guy from NSYNC") as himself taking "A Christmas Carol"-type visit through his past as a boy band singer and his trepidation about moving forward. J.C. is sleeping his way through the chorus with an eye on Nick's ex Chloe (Alona Tal), washed-up actress Brooke (Anne Heche, PSYCHO) takes a blow to the head from a pair of oversized chopsticks carried by prop man Ron (Paul Scheer) before getting dosed with Xtasy on top of her concussion (forcing Chloe to go on as understudy), Malcolm (Taye Diggs, THE WAY OF THE GUN) is feuding with co-star Brandy (Lesli Margherita, THE NUMBER 23) over a boyfriend and they decide to settle things by seeing who can land backup dancer Xavier (Diego de Tovar), danger Eric (Johnny Ray Gill, UNDERGROUND) is devastated by the loss of his pet marmoset, assistant stage manager Alex (Lauren Lapkus, ORANGE IS THE NEW BLACK) is easily overwhelmed, and bass guitarist Mickey (Zach Cregger) needs to get high to play. As Nick rushes around behind, above, and under the stage putting out fires, he realizes that there is a parallel between the play and the fear that caused him to give up his own acting ambitions. Boasting some entertaining musical renditions of one hit wonders from "Rock Me Amadeus", "Bust A Move", "Mambo #5", "I Melt With You", and Chasez's own cringe-inducing "Sex Me Gently" and some good choreography, the film is never quite manic enough to make us forget just how underdeveloped the characters and the character arcs really are (which is not unusual in musicals), but the film moves quick enough to be entertaining without focusing too much on is shortcomings.
