All That star Kenan Thompson urges Nickelodeon to 'investigate more' as he breaks his silence following 'tough to watch' documentary Quiet on Set

Just hours after Investigation Discovery (ID) greenlit a new episode of Quiet on Set, another Nickelodeon star is speaking out on the revelations: Kenan Thompson.

The 45-year-old actor launched his career as a teenager in the original run of All That in the first five seasons starting in 1994 and the spin-off Kenan & Kel in 1996.

Thompson appeared on the Tamron Hall Show on Wednesday, where he first spoke about all of the revelations about misconduct on All That and other shows created by Dan Schneider on Nickelodeon. 

The actor revealed that he never bore witness to anything improper while working for Nickelodeon, though he does want the network to investigate further.

'It's a tough subject... it's tough for me because I can't really speak on things that I never witnessed,' Thompson began.

Thompson appeared on the Tamron Hall Show on Wednesday, where he first spoke about all of the revelations about misconduct on All That and other shows created by Dan Schneider (above) on Nickelodeon.

He added, 'All these things happened after I left, basically, and Dan (Schneider) wasn't really on Kenan & Kel like that.'

'I mean, he got a "Created by" credit but it was a different showrunner, so our worlds weren't really overlapping like that, outside of All That, necessarily,' he continued.

Thompson elaborated that, 'all that negativity kind of started happening outside of like our tenure there.'

'I wasn't really aware of a lot of it, but my heart goes out to anyone who's been victimized or their families,' he stated.

'I think it's a good thing that the doc is out and it's putting things on display, stories that need to be told for accountability's sake,' he added.

He admitted the show is, 'definitely tough to watch because I have fond memories of that place.'

'And I have fond memories of my co-stars, and to hear that they have gone through terrible things like that is just... it's really tough,' Thompson said.

Hall mentioned that her production reached out to Dan Schneider and was directed to his YouTube response, and that they reached out to Nickelodeon, who responded that they, 'investigate all of the allegations,' which Thompson responded to.

'Well, investigate more,' Thompson said to applause, adding, 'because this is supposed to be a safe space, it's supposed to be a safe place for kids, and to hear all about that is just like, how dare you, you know,' Thompson said.

The first four episodes of Quiet on Set debuted on ID last week, and streamed on Max following its debut.

The documentary series chronicled the misconduct and toxic culture perpetuated by Dan Schneider on the hit Nickelodeon shows he created.

Among the more shocking revelations was Drake Bell of Drake & Josh fame revealing he was the young actor who was sexually assaulted by former dialogue coach Brian Peck.

Bell will return for the new episode of Quiet on Set, which is slated to premiere Sunday, April 7 at 8 PM ET on ID.
