Remo Williams... (1985)

Subtitled "The Adventure Begins" in the States and "Unarmed and Dangerous" in the UK, this film is something of a curate's egg.  Fred Ward plays a policeman who is thought to have died; he is recruited reluctantly by a crime-fighting team, given a new face and a new identity.  He is also given extensive martial arts training by Joel Grey who is cast as an ancient Korean Sinanju master.  When Grey is on screen, you can't take your eyes off his performance which is amusing and smart.  However he's not continuously on view and one is faced with long stretches of Ward doing his action bit.  Not that he doesn't try hard and nearly succeed, but one keeps wondering when Grey will next appear with his stinging put-downs to lift this movie to something memorable.
