TONIGHT: The Cube (ITV, 8.15pm) This game show has already enjoyed a phenomenal five series, stopping along the way to collect a Bafta award, and continues to grow in popularity even now. It's that deceptively simple concept that has the masses continually tuned in to shout at their televisions each week, and vow that they could do a better job blindfolded. But such is the frustration of The Cube. Put said people under the cold, hard stare of the studio lights, add some very intense music and a thundering voiceover to narrate their every movement, and all of a sudden, things don't look so easy after all. First up, firefighter Jason and competitive swimmer Michelle try to take on the challenges within the confines of the box - they might be fighting fit, and probably even quietly confident, but do they have what it takes?

TUESDAY: Dallas (Five, 9pm)

It's the end of an era as many Dallas fans say farewell to TV's greatest bad guy, JR Ewing. Those of us weaned on this series in the late 1970s and early 1980s may need a tissue as Larry Hagman makes his final appearance in the show that made him a media icon. If you have only warmed to Dallas because of this slick and sexy revamp, then you've missed a treat. The original was a splash of colour in a dull era . In the early days, power-crazed oil barons, a Romeo and Juliet-style sub-plot, and larger-than-life characters such as JR and arch-rival Cliff Barnes (Ken Kercheval) helped make for unmissable TV. Some may be hooked as John Ross (Josh Henderson) tries to take over Ewing Energies, and Christopher (Jesse Metcalfe) makes an alarming discovery, thousands will only have eyes for JR.

WEDNESDAY: Food Glorious Food (ITV, 8pm). Carol Vorderman fronts the series which is on the hunt for Britain's best recipe. As always, food connoisseur Loyd Grossman, vice chairwoman of the WI Anne Harrison, food writer and editor Tom Parker Bowles and the Beehive Bakery's Stacie Stewart are ready to meet the next batch of hopefuls, which this week include a father-and-son team of crab fishermen, a pub landlord and one of the oldest pastry-crimpers in the area. Given the eclectic mix right there, the judges' palates certainly aren't going to want for anything. But which recipe has what it takes to clinch that all-important place in the semi-final? Ms Vorderman enjoying her new role that little bit too much. She's recently admitted that she piled on the pounds during filming because she was required to sample the food. Luckily for us, we can enjoy it from the comfort of our arm chairs.

THURSDAY: Gogglebox (Channel 4, 10pm). In theory, the days when we all used to sit around the TV and watch the same programme together disappeared with Morecambe and Wise. However, the reality is rather different. Recent research suggests the vast majority of us still prefer to watch our TV programmes actually on a television set - even if it's in HD with a plasma screen - rather than a phone or laptop, with the average Brit spending four hours and two minutes in front of it every day. Instead of warning us that at this rate we'll all end up with square eyes, the new series Gogglebox aims to celebrate our obsession with the small screen by hearing from the experts - the ordinary viewers. A selection of Britain's most avid and opinionated telly addicts will be given the same list of programmes from the past seven days to watch and critique. The programme is narrated by Caroline Aherne.

FRIDAY: Russell Brand's Give It Up Gig for Comic Relief (BBC One, 11.35pm) Comedian, actor and presenter Russell Brand fronts a star-studded music and comedy gig in aid of this month's charity event. It features musical performances by the likes of Emeli Sande, Jake Bugg, Jessie J, Kasabian, Nicole Scherzinger, Noel Gallagher, Paloma Faith and Rizzle Kicks. The comedy part comes courtesy of such luminaries of laughter as Jimmy Carr, Jason Manford, Doc Brown, Eddie Izzard, Noel Fielding, Simon Amstell and, of course, Brand himself. Look out for: The serious bits. It might all seem like fun and games, but it's important to remember what brought so many greats from the worlds of mirth and music together - it's a charity fundraiser, with all proceeds from the show being used to help support people affected by drug and alcohol addiction. It's a subject close to the host's heart.
