Bryan Cranston had sex on a train and it did not go to plan

Bryan Cranston has shared the secrets of a successful marriage. Turns out the answer is train sex.

Cranston appeared on The Graham Norton Show on Friday night, and recounted the story of his honeymoon in Europe. 

The newlywed Cranstons were taking a transporter train through the Alps, sat in their car. The journey through the mountains was pitch black, and the travel agent had told them that there are three stretches of darkness lasting five, eight, and 50 minutes. 

Turns out 50 meant 15. So Cranston and his wife were caught out when they burst unexpectedly into the sunlight, to the horror of the Italian families either side.

Cranston tells the story with much gesticulation and mime, somewhat to the discomfort of Colin Farrell who's next to him on the couch. Still, Farrell finds room in his heart to praise Cranston at the end of the story with an admiring, "15 minutes though man!"
