Directing duo Grandmas have just signed to Black Dog FIlms, and also directed their second video for Pearl City, as two haplessly wimpy teens become our window into the world of female bodybuilding.

This follow-up to their excellent video for Down By The Tree, featuring the charismatic Tom Heyes, features two more memorable characters, played by Calum Scott and Joe Ross. They visit a seaside resort and find themselves at a Ms Universe-style show, and suitably amazed and agog.

It's another fine example of Grandmas' brand of genre-bending filmmaking, documentary and comedy slammed together to great effect. Their short film Norteños – a black comedy set in the Northwest of England - is currently on the BAFTA/Oscar film festival circuit.
