Triple bill of thrillers starring Harrison Ford. 'K-19 - The Widowmaker' (2002) is set in 1961. Captain Alexi Vostrikov (Ford) has just taken over command of the USSR's first nuclear submarine, K-19, from Captain Mikhail Polenin (Liam Neeson), who has been demoted to executive officer after stating that the vessel was not yet ready. His fears are justified when various equipment either goes missing or never materialises, but Vostrikov is ordered by his superiors to sail into the North Atlantic for a missile test - which would alert the USA of the nuclear fire-power now in the hands of their enemy. When a leak on board threatens the nuclear payload, Vostrikov realises that if it blows it could be seen as the beginning of the Third World War and orders the crew to take it in 10 minute shifts to repair the damage - thus exposing all the men to radiation. In 'Witness' (1985), detective Jon Book (Ford) is given the job of protecting a young Amish boy (Lukas Haas) who has witnessed a murder in a big city train station. Suspecting that the murder was part of a police conspiracy, Book retreats to the small farming community where the boy lives. As time passes, and despite massive cultural difference, the detective falls in love with the boy's widowed mother (Kelly McGillis). 'Witness', the first Hollywood film from Australian director Peter Weir, was nominated for eight Oscars and won two (editing and original screenplay). In 'Clear and Present Danger' (1994), an adaptation of Tom Clancy's novel, Ford reprises his role as CIA Agent Jack Ryan from earlier films 'The Hunt for Red October' and 'Patriot Games'. When his mentor Admiral James Greer (James Earl Jones) becomes gravely ill, Ryan is appointed acting CIA Deputy Director of Intelligence. His first assignment: to investigate the murder of one of the President's friends, a prominent US businessman with secret ties to Colombian drug cartels.
