The Naked Truth (1957 film)

The Naked Truth is a 1957 British film comedy starring TerryThomas, Peter Sellers and Dennis Price. Peggy Mount, Shirley Eaton and Joan Sims also appear. It was produced and directed by Mario Zampi and written by Michael Pertwee.

Knocking Dennis unconscious periodically, they finally end up in the cabin of a blimp on the way to a rendezvous with an outbound ship. To their dismay, when he comes to, Dennis refuses to go along with their plan, as he in fact never wanted to reveal any of their secrets in court. He was, in fact, winning the trial anyway. He reveals the evidence was his copies of The Naked Truth which were destroyed by the plotters earlier, unintentionally freeing Dennis of all charges. Unaware of where he is, and happy to have outsmarted his opponents again, he then steps out for some air and plummets to the ocean below. When MacGregor celebrates by shooting his pistol, it punctures the blimp, which comically shoots away into the distance.
