“White Orchid” (*1/2 out of four) was a colorless thriller about a hard-nosed investigator (Olivia Thirlby) who assumes the identity of a small-town murder victim in order to solve her gruesome death but this leads to unexpected complications and affairs she didn’t foresee. No relation to the Mickey Rourke cult classic “Wild Orchid” from 1989 but come to think of it, this rips off another thriller with Mickey Rourke “White Sands” from 1992. It’s hard to assume the identity of a dead person when the movie itself is dead to begin with. Jennifer Beals and John Carroll Lynch are wasted in supporting roles as cops.
