Dead Again (1991)

Synopsis
Set in contemporary Los Angeles as well as the Los Angeles of the 1940s, Dead Again explores a romance between two star-crossed lovers -- and the doomed passion they shared in their last lifetime. Los Angeles detective Mike Church (Kenneth Branagh) comes to the aid of mute, amnesia-victim Grace (Emma Thompson) and falls in love with her. He sets out to discover her true identity and the source of her terrible nightmares. Mike is aided in his investigation by hypnotist/furniture dealer Franklyn Madison (Derek Jacobi) who discovers that in a past life Grace was Margaret Strauss (also played by Thompson), who may have been mudered by her husband Roman (Branagh). ~ Linda Rasmussen, All Movie Guide
