Sam Ryder, the UK's impressive runner-up at this year's Eurovision Song Contest with Spaceman, returns to action with another irrepressible performance in Alex Southam's celebratory song-and-dance production for Somebody.

For the unapologetically sunny track, Southam puts his own spin upon a great tradition of videos that have reimagined the old-school Hollywood musical. And that turns out to be pretty much the ideal vehicle for Ryder's larger-than-life persona.

In a picture-perfect European city, Ryder bounces through main street, finding dance partners at the café and cinema, launching himself from a scissor lift, and stopping off for a quick snip at the barbers before multiplying before our eyes in his big finale. He busts some unfeasible moves in a various ways that recall those classic Spike Jonze videos for Bjork's Oh So Quiet and Fatboy Slim's Weapon Of Choice. And finally director and artist put there own playful twist on the classic Texas Switch.

"The brief for the video came with a few buzz words - fun, quirky, sunny, bright, bold and joyful - and so that's exactly the sort of video we set out to make," explains Southam. "A handful of film references were shared, one of which is probably glaringly apparent in the final video. But we wanted to up the ante and make it feel super-playful - with it's tongue firmly wedged in its cheek - so that's when the use of doubles and the Texas Switch came into play."

The video was filmed in Belgrade, on what Southam describes as "one of the most bonkers backlots I've ever seen." It was also in the middle of the extreme heatwave that has scorched Europe this summer, but "we had an absolute blast making it," he says.

"I want to call out DoP Murren Tullett’s stellar work and Jay Revell on choreography duty - those boys came correct. But to be fair everyone smashed it. I'm still gutted we didn’t get to use the jet-ski set-up - but I did throw a man off a scissor lift, so its all swings and roundabouts."

As for Sam Ryder, can he really be as unfeasibly cheerful as he seems? "Sam is the real deal," asserts Southam. "A genuine and super upbeat chap always with a smile. So we wanted to capture him spreading those good vibes around and highlight his infectious personality."
