EastEnders 8pm, BBC1 The first-ever live episode of the BBC's flagship soap, now celebrating 25 years on television, in which Ricky and Bianca hold their wedding knees-up and Archie's killer is finally unmasked. Then it's over to BBC3 straight afterwards, where Archie's real-life son, George Lamb – with his funny bowtie and rolled-up trouser legs, like a confused academic off for a paddle – will interview the still-panting cast live in Albert Square. There's also backstage footage shot in the run-up to tonight's momentous happenings. Exciting, isn't it? The Mentalist 9pm, Five Get past the show's title, the distraction of a male lead being constantly addressed as "Jane", Simon Baker's curly, highlighted hairdo, and an improbably juvenile and photogenic team of criminal investigators, and you have here a perfectly serviceable procedural drama, distinguished by Jane's clever line in pseudo-psychic observational techniques. Tonight's second series opener, a workaday whodunit, is made watchable by a running joke involving the question, "Do you know a man named Miles Thorson?" The Bubble 10pm, BBC2 David Mitchell hosts a new comedy-news quiz. Now that's what we call a game-changer. No previews available, as it's going to be topical news from the week, but it sounds like Celebrity Big Brother meets Call My Bluff and Mr & Mrs: three slebs are locked in a "media-free zone" for three days and, on exiting, have to pick out the genuine news stories from the invented ones. Tonight, it's the turn of Frank Skinner, Reginald D Hunter and some poker player to sort out the headlines from the head-lies. Life 11.05pm, FX Damian Lewis stars here as detective Charlie Crews – convicted, but ultimately pardoned for a crime he did not commit, and now back on the police force, considerably stranger than when he left it. Tonight, his unique psychological skillset is brought to bear when a body is found taped to a chair at the bottom of an empty swimming pool. It turns out this is the end result of a sinister steroids racket, a lion's mouth into which Crews is only too happy, in his eerily smiling way, to put his head. All the while, echoes of his own backstory rumble ominously.
