Breaking Bad stars Bryan Cranston and Aaron Paul attended a celebration of life ceremony for their late costar, RJ Mitte, who tragically died by suicide on October 13 at 34.

Cranston, 70, who played Mitte's onscreen dad Walter White on the long-running AMC series, looked solemn in a black suit and tie while mingling with Mitte's family and friends, who gathered at Hope Lutheran Church in Hollywood on Saturday to pay their respects.

Paul, 47, who played Jesse Pinkman, White's young and volatile partner in crime, wore a dark blue button-down shirt and dark trousers and shielded his eyes behind opaque shades.

Breaking Bad costars Bob Odenkirk, 64; Jonathan Banks, 79; and Raymond Cruz, 62, also showed up to honor Mitte, whose devastating final days were recently detailed.

Mitte's Switched at Birth costar Gilles Marini was seen at the somber event, wearing an all-black ensemble. 

Mitte's mother, Dyna Mitte, and his sister, Lacianne Carriere, were present as well.

Following the service, guests moved on to a nearby bar to continue sharing memories and stories, according to TMZ.

A previous celebration of life ceremony had been held on October 16 in Mitte's hometown of Brownsville, Texas, where family and community members gathered to honor his work.

Mitte, who was diagnosed with cerebral palsy around three years old, was found dead by his mother, who went to check on him at his house after he had missed her call around 11am.

The manner of death was ruled a suicide by hanging, according to an official inquest report viewed by Page Six.

His mother, Dyna, spoke to The Hollywood Reporter about the tragedy and admitted 'there were concerns' about his mental health, but she said she encouraged him to seek professional help.

'It was more about the conversations we were having – not just with me, but with his team and friends,' she said.

'There were concerns. That's why I encouraged him to talk to a counsellor. I told him to talk to a therapist and share his feelings and how he saw things,' Mitte's mother added.

The late actor's devastated sister, Lacianne, penned a heartrending tribute to her brother on Instagram last month, writing: 'There are just no words. You were just here. Your strawberry Fanta was still sitting on my coffee table when I got the call. Life hasn't felt real since then.

'RJ, you were my everything. I just lost my other half. I lost my brother, but I also lost my father,' she went on.

'Every single aspect of my personality is because of your influence. My music taste, my film taste, the video games I love. Because of you, I am a collector. You taught me that even the smallest piece of paper can be a precious memory later on.'

She concluded: 'I loved you completely. And you loved me the same. That's all. The rest is confetti.'

Mitte's younger sibling also broke down in tears while delivering a moving eulogy at his October 16 memorial service.

'My mom was a single mother, and when I was two weeks old, she was in an accident that paralyzed her from the waist down for the first few years of my life,’ Lacianne described.

‘And my brother immediately took on the father role. I don't have many words that I can put together, but all I can say is that every part of me is RJ.'

In an Instagram post shortly after the announcement of Mitte's death, Cranston shared that he was in 'deep despair.'

'I met him when he was only 14 years old when he was cast as Walter White Jr., a part he played with such joy and enthusiasm,' Cranston wrote.

'Born with cerebral palsy, he never – ever – allowed that challenge to be an excuse for anything. He met the demanding shooting schedule head on with great determination.'

Cranston went on to reveal they were in touch only a 'few weeks ago,' writing: 'All that promise and potential now is such a loss. It is especially devastating to hear that he took his own life.

'Why? We were texting each other just a few weeks ago – figuring out when we could meet for lunch. I don't know if that lunch would have changed his future.

'But I do know that I loved him, and thoroughly enjoyed being with him throughout the years on the series, and after the spotlight on Breaking Bad dimmed.'

Though best known for playing Walter White Jr in Breaking Bad, Mitte appeared in many other television series including Switched at Birth (2014), Robot Chicken (2016), Now Apocalypse (2019), and The Guardians of Justice (2022).

His film roles included the sci-fi horror The Recall (2017), River Runs Red (2018), Standing Up for Sunny (2019), The Oak Room (2020), and Triumph (2021).

Mitte was also an avid disability and cerebral palsy advocate who used his status as an actor and public figure to challenge stereotypes and promote inclusion and authentic representation in Hollywood.

'People perceive disability as a weakness, as an illness, as something that needs to be cured, and we have to fight against that,' Mitte told Vice in 2013.

'Someone said, "What's wrong with you?" And I was like, "What's wrong with me? What's wrong with you? I’m fine, man."'
