The big screen beckoned the following year and Mark took the lead in JUST FOR FUN. Promoted as “The big teen musical made just for you,” JUST FOR FUN is set in a mythical county, not unlike Britain, that is approaching a General Election. The two main parties are worried about the chances of gaining a majority and agree to give teenagers the vote. Mark celebrates this news by singing ‘Vote For Me’ [picture below] and decides to form his own political party [picture below] whose aims are strictly ‘Just For Fun.’ Mark’s girlfriend, Cherry, who thinks he is neglecting her for politics is reassured as he sings ‘Happy With You.’

Mark’s illustrious co-stars included Dick Emery, Irene Handl, Hugh Lloyd, Jeremy Lloyd, Richard Vernon, Reginald Beckwith, Harry Fowler and Frank Williams. Cinematography was by Nicolas Roeg who later graduated to great acclaim as a feature director.

Pop was represented by DJ’s Alan Freeman and David Jacobs with performances by Joe Brown, Bobby Vee and the Crickets, Kenny Lynch, Brian Poole and the Tremeloes, Clodagh Rodgers, The Tornadoes, and the Springfields [including Dusty].

So popular was Mark in his film debut that a further film JUST FOR YOU was made. Mark is seen with Diana Dors taking delivery of his first car – an Austin Healey Sprite. This period also encompassed THANK YOUR LUCKY STARS and two appearances on ITV’s BIG NIGHT OUT, first with Kathy Kirby and secondly with Kenneth More. Mark then had his own six part TV series CALL IN ON WYNTER.
