Jonathan has all the ingredients to impress some visiting US television executives - special effects, a horde of zombies, grand sets and some totty - but he also wants his team to be as American as possible, meaning the arrival of baseball caps and a basketball hoop. However, even the cast members selected fail to save him when his plans start to unravel. If you'd rather a dose of reality, try Rocket Science (9.00pm, BBC2).

How's THAT for Friday night viewing?! He aims to show the teenagers how fireworks have their origins in a marriage of chemistry and physics, but gets off to a bad start with a less-than-impressive firework display.
