In 1957's "Tip on a Dead Jockey", Robert Taylor drives a Mark Minx convertible.
In 1963's "Under the Yum Yum Tree" starring Jack Lemmon, there is a Series Minx convertible parked outside his apartment house.
In 1963's "The Haunting", Julie Harris drives a very nice Series II Husky
In 1965's "Help" starring the Beatles, Ringo gets kidnapped by a mad scientist and his henchman. They put him in the trunk of a Series Minx De Luxe saloon, and drive off. George hops on the back. They crash into a tree in an attempt to throw George off. The car stalls. While they're trying to start the car again, George nonchalantly loosens the lug nuts on one of the rear wheels. When they drive off again, the wheel falls off, and George and Ringo escape from them.
In 1967's "The Graduate", Dustin Hoffman takes Katherine Ross out on a date. As they're walking along the street, we see a Series II Husky drive by. Later, they're eating at a drive-in fast food place, and the car next to theirs is a Series Minx convertible with the radio blaring. Hoffman asks them to turn it down, but the Minx driver misunderstands, and turns it louder.
In 1981's "Charlie and Great Balloon Chase", the leading man (I don't know his name) drives a red Series Minx convertible. The sound of the engine is not correct, though. Undoubtedly, dubbing was done for this picture.
