Primeval (ITV1, 5.30pm)
This is the penultimate helping of season five, and co-creator Adrian Hodges has saved the best for last.
It remains to be seen whether series six will eventually emerge after next week’s finale, but whatever happens to the ITV1 saga, you can bet that good old T-Rex and company will be terrorising new generations of kids long after we’ve all turned into ancient wrecks ourselves.
There’s a fine cast including Ciaran McMenamin, Andrew-Lee Potts, Hannah Spearritt, Ben Mansfield, Ben Miller and Alexander Siddig but the real stars of the show are those CGI dinosaurs.
Big Dance 2012 (Channel 4, 4.30pm)
Behind-the-scenes coverage of an ambitious event led by choreographer Wayne McGregor as he pulls together 35 troupes – around 1,000 performers – to carry out an epic 40-minute work in Trafalgar Square in what is a unique and memorable addition to the London 2012 Festival.
Preparations went on for several months, and the final performance itself takes place on Saturday.
Blackout (BBC One, 9pm)
Corrupt politician and stranger in his own life Daniel Demoys (Christopher Ecclestone) wakes up from another drunken Blackout to find his shirt covered in blood. Realising that he might be responsible for murder, Daniel starts putting his life in order and after a dramatic act of redemption, finds himself in the running for London Mayor. However, success could be sabotaged by the evidence of a woman who saw him that night at the scene of the crime, and as Sylvie (MyAnna Buring) is drawn irresistibly into Daniel’s dark world, the web of lies and deceit surrounding them grows ever more tangled.
CSI: Crime Scene Investigation (Five, 9pm)
An Alice-in-Wonderland-themed wedding in Las Vegas reaches a tragic close when two armed assailants manage to escape with the congregation’s cash and valuables, leaving the groom dead from a gunshot wound.
However, it was not a bullet that killed the would-be husband, but a button lodged in his brain.
Look out for guest star Jaclyn Smith, a pin-up as one of the original Charlie’s Angels.
Restoration Home (BBC Two, 8pm)
Caroline Quentin follows in the footsteps of people like Griff Rhys Jones and George Clark in helping to save some of our architectural gems. What Restoration Home does brilliantly is show that there is far more to a property than bricks and mortar. Through a mix of research and scientific wizardry, the series is superb at breathing life into crumbling buildings and revealing just how much life each one has witnessed.
The Hotel Inspector (Five, 9pm)
Award-winning hotelier Alex Polizzi comes to the rescue of another ailing hotel in dire need of her expertise, injecting her savvy business know-how to help families struggling to keep up their trade. This week, Alex travels to the Caspian, a 10-bedroom hotel in Ealing, West London, owned by the Samari family. With an occupancy rate of just 10 per cent, what exactly are the Samaris and the Caspian doing wrong?
Phil Spencer: Secret Agent (Channel 4, 8pm)
Phil Spencer’s campaign to kick some life into the nation’s flagging property market continues.
This time he goes undercover in Scotland, trying to get offers on two houses not far from Glasgow’s busy city centre.
One house is a 50s throwback, the other an 80s revival, and neither is what the buyers of Glasgow’s swanky suburbs want in a family home.
