Query: A good thriller

Based on Frederick Forsyth's book. A story about a British agent (Michael Caine) trying to stop a Russian agent (Pierce Brosnan) who tries to detonate a bomb. It is rather well made and I am surprised after the popularity of Pierce as James Bond this movie still has not seen a DVD release. Please,whoever owns the right release this on DVD.
