Strictly Come Dancing (BBC One, 7.15pm)
The launch show pairs the celebrities with their professional dance partners, and for Irish viewers, all eyes will be on Daniel O’Donnell, a man you wouldn’t normally associate with lithe grooving. Music performances on the show come from Jess Glynne and Gregory Porter.
The X Factor (TV3, 8.15pm)
The biggest singing competition on the planet returns exclusively to TV3 this autumn with a whole new presenting line up and judging panel.
X Factor veterans Simon Cowell and Cheryl Fernandez-Versin are back to pave the way for new recruits, pop sensation Rita Ora and much-loved radio DJ Nick Grimshaw.
Our favourite Xtra Factor duo, Olly Murs and Caroline Flack are making their return but this time it's for the main show.
The new series will also see the auditions move out of the rooms and straight into the arenas, with hopefuls having to perform in front of an arena audience from the start in the hope of making it through to the next stage.
Electric Picnic 2015 (RTÉ2, 9pm)
Even allowing for the difficulties in covering a live festival, last year’s Stradbally offering from Stradbally was rather patchy.
You’d imagine we’ll get an improved package tonight of live performances, celebrity interviews, and onsite reports from Eoghan McDermott, Jenny Greene, Al Porter and Blathnaid Treacy (remember her as one of Biddy and Miley’s daughters in Glenroe?).
9/11: Elite Rescue Cops (More4, 9pm)
This fascinating one-off documentary explores the heroism and sacrifice of the New York Police Department’s Emergency Service Unit on the day when Osama bin Laden’s terrorists launched a catastrophic attack on the World Trade Center.
Arriving within five minutes of the strikes, this specially trained team was the first on the scene and their bravery in the face of danger saved countless lives - but the officers paid a terrible price when almost half of their number were lost in the rubble of the Twin Towers.
It Was Alright in the 1970s (Ch4, 9pm)
Last year, Channel 4 brought us two programmes in which Matt Lucas reminded us of some of the casual sexism, racism and homophobia that used to pass for light entertainment in the 1970s.
However, it seems they barely scratched the surface, as now Lucas returns to narrate a brand new series of eyebrow-raising clips.
The first edition shows that even in an era of sexual liberation and the rise of feminism, chauvinistic attitudes were still pervasive in everything from sex education films aimed at children to chat shows.
The programme also examines the use of lazy national stereotypes and laid-back attitudes to health and safety, while asking whether these programmes were a fair reflection of society’s views, and how modern viewers should react to them.
Up For The Match (RTÉ One, 9.15pm)
Gráinne Seoige and Des Cahill host the traditional pre-All Ireland show of music and chat from representatives of Kilkenny and Galway.
Immortals (Channel 4, 10.00pm)
(2011) Many centuries ago, the Gods waged war against the Titans and imprisoned these creatures within Mount Tartaros, within a cage that can only be broken by a bolt from the mythical Epirus Bow.
Megalomaniac King Hyperion (Mickey Rourke) and his hordes declare war on the Gods by ravaging the land in search of the bow.
Ancient law prevents Zeus (Luke Evans), his daughter Athena (Isabel Lucas) and the other Gods from intervening in mankind’s conflict, so they watch with mounting dread as Hyperion slaughters everyone who gets in his way.
Strapping Theseus (Henry Cavill) witnesses his mother Aethra (Anne Day-Jones) falling to the swords of Hyperion’s hordes. Theseus seeks vengeance but many obstacles stand between him and his showdown with Hyperion, including the hulking Minotaur (Robert Maillet).
Boyz N The Hood (BBC2, 11.10pm)
(1991) John Singleton’s debut blew audiences away when it was released all those years ago in 1991, offering a gritty exploration of the social problems of the time.
It also marked the beginning of a remarkable career for Cuba Gooding Jnr, who went on to scoop an Oscar for his role in Jerry Maguire.
In this sensational film he plays Trey, a young man struggling to come to terms with life on the dangerous streets of South Central LA, along with his two pals, who find it marginally more difficult to cut themselves off from a life of crime.
Sterling support comes from Laurence Fishburne, Ice Cube, Morris Chestnut and Nia Long.
The Double (Channel 4, 12.15am)
(2013) Director Richard Ayoade (Submarine) puts his distinctive spin on Dostoevsky’s novella, updating the action from 19th century Russia to surrealist modern-day America.
Simon (Jesse Eisenberg) is a shy, socially awkward office worker who is overlooked by everyone in his unedifying existence including his boss, his mother and the woman of his dreams, Hannah (Mia Wasikowska).
He feels powerless and isolated in an indifferent world. New co-worker James (Eisenberg) upsets the balance – he is the physical double of Simon but personality-wise, his exact opposite: confident, engaging and enviably charming around women.
Slowly but surely, James begins to take over Simon’s life and the timid office worker must find the courage he has kept hidden for so long to fight back and retain his identity.
