When Miranda Met Bruce (BBC One, 7.30pm)
From time to time, television greats will come together for a ratings-pleaser of a show that really lets us get inside the minds of some of the celebrity sphere's most private characters.
However, on this occasion, even the hugely talented award-winning comedy writer Miranda Hart must have had to pinch herself to be working alongside none other than Sir Bruce Forsythe in a programme that celebrates the latter's incredible 70 years in show business.
Downton Abbey (ITV, 8pm)
It's series four of Britain's most successful – and most publicised – period drama in years (pictured).
Once more it centres on the wealthy Crawley family and their servants, and takes place in the early Twenties. As the new series begins, it's six months since the death of Matthew Crawley, a plot twist that left viewers worldwide shocked in last year's Christmas episode.
So, while new mother Mary is struggling to come to terms with Matthew's demise, Violet and Robert clash over their approach to the situation. Elsewhere Jimmy finally takes a shine to Ivy; a memory from Carson's past rears its ugly head, and Mrs Hughes tries to help grief-stricken Isobel.
Tom Kerridge's Proper Pub Food (BBC Two, 8.30pm)
The idea of 'proper pub food' will mean different things to different people. After all, in some parts of the country it's a microwaved meal served in the plastic container, or breaded cod plonked on your plate after you ordered plaice because the cook forgot to label the box in the freezer.
Not so in Tom Kerridge's establishment. He's the only British chef to have earned two Michelin stars by cooking in a pub. He kicks things off with dishes perfect for serving up to groups of friends. He demonstrates how to prepare slow-cooked shoulder of lamb with pommes boulangère', and mussels in ale for a barbecue night.
The Wrong Mans (BBC Two, 9pm)
Unless you've been living on Mars for the past few weeks, you can't fail to have noticed the adverts for The Wrong Mans.
It was written by and stars James Corden and Mathew Baynton as Phil and Sam respectively. They work in the offices of Berkshire County Council, and their lives are turned upside down one day after Sam answers an abandoned mobile phone at the side of a car crash only he witnessed.
The voice on the other end of the line states: "If you are not here by five o'clock, we will kill your wife." But Sam isn't married, so who is the message meant for, and why has a woman been kidnapped?
Gogglebox (Channel 4, 10pm)
These days, you can watch your favourite programmes on demand and on the go, so why do many of us still prefer to actually settle down on the living room sofa and watch them on the telly?
The first series of Gogglebox supplied a possible answer – sometimes the running commentary provided by our friends and family is more entertaining than the actual programmes. They set up a camera in households across the country, and let us see what these groups of families, friends and flatmates really thought of the programmes.
The results were funny, insightful, sometimes slightly surreal and also offered us a fascinating glimpse into the viewers' own lives. And most of them are back for the second run, along with a couple of new recruits as they discuss the big programmes from the past seven days.
