Escape Route (1952)

This is actually quite a reasonably paced little cold war thriller. It sees FBI man George Raft ("Rossi") and his British counterpart "Sally" (Joan Miller) seek to get to the bottom of a mystery involving the disappearance of several high-level nuclear scientists. The plot is pretty procedural; it is clear from early on whom the perpetrator is, but their pursuit of him and of his captives is quite well produced, scripted and though maybe it does lack much of any sense of peril, it is still an enjoyable enough afternoon feature that proves Raft had some degree of versatility. You are unlikely to recall it afterwards, but it does it's job for 80 minutes.
