DailyEdge.ie rounds up the TV shows that you’ll be tweeting about tonight and talking about tomorrow.

Ray D’Arcy Show (RTÉ One, 10.05pm)

Tonight, Ray has quite the lineup joining him in studio for a bit of a chat. Firstly, and probably most importantly, he’ll welcome Room to Improve’s Dermot Bannon to have a natter about being Ireland’s favourite architect. Father Ted’s Pauline McLynn is also in, as well as gas Welsh rugby ref Nigel Owens. We might be in for a good one here. #RayDarcyShow

Zodiac (BBC Two, 10.50pm)

David Fincher’s eerie and excellent portrayal of the hunt for the serial killer Zodiac in 1960s and 1970s San Francisco. Jake Gyllenhaal plays the newspaper cartoonist who becomes obsessed with his capture and his cryptic messages, while Mark Ruffalo is tasked with the actual police work to find him. Gripping stuff. #Zodiac

Britain’s Got Talent (TV3, 8pm)

We’re well into the tenth season of BGT this year, and we’re getting to the end of the travelling audition tour. Reports suggest only one Golden Buzzer remains, meaning one of last week’s acts was impressive enough to tempt either Ant and Dec or Simon Cowell to put them through to the semis. Always a bit of craic on a Saturday evening. #BGT

Everyone’s talking about… Linda Martin’s performance on last night’s Late Late Show

It was a remixed version of her Eurovision song, and people couldn’t stop talking about it:

Whoops!

We couldn't find this Tweet

It was surreal:

Whoops!

We couldn't find this Tweet

Oh Ireland:

Whoops!

We couldn't find this Tweet

What a performance.

Or flick over for…

• 2012 (RTÉ 2, 9pm) Global catastrophe on a John Cusack scale.
• Alien (Channel 4, 11.25pm) An absolute classic.
• Match of the Day (BBC One, 10.30pm) The league might be sewn up already, but there’s still plenty to play for below.
• Rugbaí Beo (TG4, 10.50pm) The final round of PRO12 fixtures sees all the Irish teams involved – and it could be a bit of a nailbiter.
