Ben Whishaw and Kate Winslet were among the winners at the Bafta TV awards ceremony at Royal Festival Hall in London on Sunday evening.
Winslet, 47, won the best actress award for her performance in Channel 4's drama I Am Ruth, which sees her play a mother and her real-life daughter Mia Threapleton a daughter trying to work through emotional turmoil on-screen.
In an emotional speech, the Titanic star said: "If I could break it in half, I would give the other half to my daughter, we did this together, kiddo."
The actress also said that "small British television dramas can be mighty" and mental health stories such as this one "need to be heard".
Winslet added: "To people in power, please criminalise harmful content, we don’t want it… to any young person listening, please ask for help, it will be there just ask for it."
It was the second appearance from Winslet who joined the team of I Am Ruth on stage earlier in the night as they accepted the Bafta TV award for single drama.
Meanwhile, James Bond and Paddington star Whishaw also collected a top acting gong during the ceremony for his performance as an under pressure doctor in BBC series This Is Going To Hurt.
On stage, the 42-year-old actor said "everybody in the show is just mind-blowing" and "most of all thank you, Adam Kay, for writing this wonderful role". He added: "I’m very humbled, and blessed."

The medical drama is based on Kay’s book This Is Going To Hurt: Secret Diaries Of A Junior Doctor which chronicles his work training to be a doctor in the NHS.
It was also the second time Whishaw had appeared on stage to collect the prize for most memorable moment for his sketch as the voice of Paddington Bear featuring the late Queen in honour of her Platinum Jubilee celebrations.
The ceremony also saw Channel 4 comedy Derry Girls win two awards, with creator Lisa McGee collecting the award for best scripted comedy and Siobhan McSweeney winning best female performance in a comedy programme for her role as Sister Michael.
They weren't the only Irish winners on the night as Sharon Horgan and Anne-Marie also picked up awards for their involvement in Apple TV+ series Bad Sisters.
Meanwhile, British athlete Mo Farah won a Bafta award for his BBC One documentary The Real Mo Farah which revealed he had been illegally trafficked to the UK as a child.

Collecting the best single documentary prize, the four-time Olympic champion dedicated the award to "children who are being trafficked".
In his speech, he said: "The kids have no say at all, they are just kids and no child should ever go through what I did, I hope my story shows they aren’t alone, we are in it together."
The 40-year-old thanked the team at the BBC because it "wasn’t easy" to film and he wouldn’t have been able to it "without them", while his wife Tania Nell said it was the couples children who "empowered" them to tell the story.
It was also a big night for entertainment programmes, as ITV’s The Masked Singer fought off competition from Ant And Dec’s Saturday Night Takeaway and Strictly Come Dancing to win best entertainment programme.

Host Joel Dommett joked in his speech: "I really didn’t expect this, Strictly normally wins everything.
"Thank you so much to ITV firstly for believing in this silly show, it is so silly and it’s so wonderful, it has brightened up so many families and homes."
Meanwhile, the reality and constructed factual award went to hit BBC One psychological adventure show The Traitors which sees strangers play "the ultimate game of detection, backstabbing and trust" at a Scottish Highlands castle in the hope of winning big.
Host Claudia Winkleman, 51, later picked up the Bafta for entertainment performance for the series, saying she didn’t want to get emotional as her mascara "will run" before asking her husband: "Please, can we have a dog?"
She also "thanked" her mother and father and said it was "for you" before saying: "You can’t have it… no, but you can touch it."
