Another great film that needs to be restored.
"Call It Murder" is released by GMVS Entertainment, a company known for putting out bad transfers on DVD. "CIM" is no exception, and the dvd has terrible sound and picture.
Though it's not GMVS Entertainment's fault certain films have not been restores, I wouldn't spend too much money on these releases.
Look for a region 1 release, it might be better. The film is also know by the title "Midnight" in the US, you might find a even better transfer on VHS.
