Love hasnt been like this since 1943

n London during World War II, Lieutenant David Halloran (Harrison Ford), an American bomber pilot serving with the Eighth Air Force based in the United Kingdom, and Margaret Sellinger (Lesley-Anne Down) a British nurse, meet on Hanover Street in a chance encounter during The Blitz.
They meet again two weeks later in a secret assignation on Hanover Street. Although she is married, Sellinger and Halloran rapidly fall in love. She tries to resist, but is drawn to the charismatic American. By contrast her husband Paul Sellinger (Christopher Plummer) is, by his own description, suave, pleasant, but fairly dull. A former teacher, he is now a trusted member of British intelligence.
Halloran is subsequently sent on an undercover mission in Nazi-occupied France to deliver a British agent (Lieutenant Wells). At the last moment, Sellinger takes the place of the agent, and himself joins the mission. His reasons are initially unclear, but he slowly reveals that he wants to prove himself.
Flying over France, his aircraft is hit, with the crew being killed, except for the sole survivors, Halloran and Sellinger. In occupied France, the two have to work together, especially after the agent injures his ankle. Sellinger's mission is to arrive at the German headquarters in Lyon and, posing as an SS officer, photograph an important document that lists the German double-agents in British intelligence. Halloran agrees to help Sellinger. Making contact with the local French resistance, they disguise themselves as German SS officers and steal the documents. SS troops raise the alarm but the pair manage to escape after a lengthy car chase, and make it back to the same farm where they had received assistance. However, they are betrayed by a collaborator and are forced to flee again, pursued by hundreds of Nazi troops, but successfully make their escape.
In London, Sellinger's wife finds out that Halloran and Sellinger are together and have come back home, with her husband wounded, but alive. Going to visit him in the hospital on Hanover Street, she meets Lieutenant Halloran for the last time. They embrace and kiss, and he tells her that he loves her "enough to let her go", she goes in to see her husband, while he goes out into Hanover Street, where the love story had begun.

Hanover Street benefited at the box office from Harrison Ford's post-Star Wars fame, but received decidedly mixed reviews from critics. Vincent Canby referred to that fame in his review:
"Every now and then a film comes along of such painstaking, overripe foolishness that it breaks through the garbage barrier to become one of those rare movies you rush to see for laughs. What Peter Hyams has achieved with Hanover Street, his new film about a wartime romance set in the London of 1943, is a movie that is almost as funny as Woody Allen's What's Up, Tiger Lily? which, if you remember, was a straight-faced Japanese spy picture that Woody took over and dubbed with a hilariously knuckle-brained English-language soundtrack. The clichés were everywhere, but always just slightly out of place and inappropriate. This pretty much describes the unfortunate method of Hanover Street, which looks as if Mr. Hyams had studied every popular romantic drama, from A Farewell to Arms to Love Affair and Love Story, and then, when he left the screening room, had been hit on the head with a brick....[Ford's] more of a comic-strip character here than he was in Star Wars, which was a live-action cartoon."[11]
Variety said the film is "reasonably effective as a war film with a love story background. Unfortunately it’s meant to be a love story set against a war background." It also notes: "Down again distinguishes herself in a role that doesn’t seem up to her standards, while Ford back in the pilot’s seat again projects an earnest, if dull, presence. Rest of the cast is under-utilized. John Barry has contributed a score that evokes Douglas Sirk's glossy tearjerkers of the 1950s."[3] Film reviewer Leonard Maltin had a similar critique, calling Hanover Street, "slick, but contrived and unconvincing."[12]
The film has developed a following among movie fans and aviation enthusiasts due to the flying sequences.[13] The pairing of Harrison Ford and Christopher Plummer and a plot involving a moving love story, was also notable
