“The Silent Hour” (*** out of four) was a tensely done action melodrama about a hard-boiled cop (Joel Kinnaman) with hearing loss and a deaf witness (Sandra Mae Frank) to a murder who find they have only themselves to rely on as they have to outsmart a sinister conspiracy involving other cops (Mekhi Phifer, Mark Strong, and others) and thugs that are out to kill them. Sharply made and directed and has sturdy momentum and final 45 minutes will have you holding on tight. Strong and Phifer stand out as usual in strong supporting cast.
