Loads to watch tonight as sublime spy drama The Americans is back for a final run, there's a documentary about swimming in Ireland, and it's goodbye to Alan Partridge, The Walking Dead and The Looming Tower . . .

Pick of the Day

The Americans, 12.15am, RTÉ 2

I'm tempted to make this pick of the day for Monday and Tuesday, given the superb quality of the show and its post-midnight timeslot.

Easily one of the greatest TV shows of the last decade, The Americans has inexplicably been largely ignored on this side of the Atlantic, despite numerous awards and universal critical acclaim Stateside.

As the sixth and final season of this immensely taut drama about Soviet agents living as an American family during the height of the Cold War opens it's 1987, and things have moved on.

Philip has become a full-time travel agent, Henry's a promising ice hockey player at boarding school, Paige is in college and a Soviet agent-in-training, while Elizabeth is exhausted and resentful from her KGB case load.

America's Child Brides, 11.00pm, BBC One

This looks like being a pretty chilling investigation into the US laws that allow older men to marry girls under the age of 16.

Ellie Flynn travels to the USA to visit states poised to reconsider their child marriage laws. For example, South Carolina is considering closing its 'marry-your-rapist' loophole that allows girls under 16 to marry if they are pregnant and have a parent’s consent.

The Old Man and the Gun, Sky Store

Screen legend Robert Redford takes his final bow in what is apparently his final role, in the story of another man’s last hoorah. It's a marvellous career-closer.

Based on the true story of Forrest Tucker, Redford plays the 70-year old man as he escapes from San Quentin to act out a string of heists that confounded the authorities and enchanted the public.

Wrapped up in the pursuit are detective John Hunt (Casey Affleck), who is enthralled by Forrest’s craft and ingenuity, and his romantic interest (Sissy Spacek) who finds it easy to look past his chosen occupation.

Ending Tonight

This Time with Alan Partridge, 9.30pm BBC One

It's a been a pretty impressive comeback for Steve Coogan's legendary character – not least the Saint Patrick's Day episode where UK viewers were treated to rousing choruses of 'Come Out Ye Black and Tans' and 'The Men Behind the Wire'.

In this finale, faced with some of the toughest challenges that live TV can throw at a man - rancour behind the scenes, a viewer in danger, a segment on ladies fashion - Alan calls on ‘Sidekick’ Simon Denton to step up to the plate.
