I've seen Suddenly a couple of times now and found it quite gripping.

A rail worker receives a message telling him that the President is to pass through Suddenly at 5 pm. A bunch of crooks find out about this and terrorise a family, whose home overlooks the station, giving the terrorists the perfect vantage point to assassinate the President. After all this, the President's train goes through non-stop and the crooks get their comeuppance.

The cast in Suddenly includes Ol Blue Eyes himself, Frank Sinatra and is joined by Sterling Hayden (The Asphalt Jungle) and Nancy Gates (World Without End, The Atomic City).

Suddenly is a must see for all old movie fans. Very gripping.

Rating: 3 and a half stars out of 5.
