How it begun

In 1979, he learned to cut films on a Steenbeek editing table on the endless film stripes of slapstick comedian stories. Luckily, his father Heinz Caloue worked in the business as an author and as a synchronous director for plenty of slapstick series with Stan Laurel and Oliver Hardy and the unforgettable Buster Keaton among the whole bunch of slapstick stars at that time. Martin worked alongside his father at his company for three years and has therefore learned the business from scratch.

Even today, people love to watch the series online. These series have been aired on the ZDF, (Zweites Deutsches Fernsehen) – the German Television broadcaster – in its importance like the BBC. They even entered a strategic partnership in 2019 to develop and co-produce world-class content.
