The late-night interview was far from conventional, with McGowan coming out in sweats (and denouncing the concept of suits), before sharing a story about getting arrested for "turning on to Courage St."
When Colbert delves into last year's deluge of accusations against Harvey Weinstein, McGowan declares herself the "architect" of the movie mogul's downfall.
She goes on to address the culture at large, saying "I think we can do better societally."
"There's a bus on fire with a madman in a blindfold, and everyone's talking about it like it's nice. It's not nice," she said, before warning viewers to "shake it up."
Colbert was quick to point out that nothing she said was factually incorrect.
McGowan has already addressed the appearance on social media, fighting back against the media's portrayal of her as "bizarre," arguing that she's just done with following the status quo.

1) I had fun (as much as one can have in this alternate reality) on the @colbertlateshow any press framing it as "bizarre" I just have a different personality than you. I don't follow protocol. And I will talk about WHAT I WANT. I requested a Dick Cavett free form hangout.— rose mcgowan (@rosemcgowan) February 1, 2018
2) I am bored of formats and questions. I am done with traditional structure. If you're not with the fake tradition of traditional promotional "appearances" then by all means, stay in your square, but DO NOT APPLY TO ME . @TheAVClub— rose mcgowan (@rosemcgowan) February 1, 2018
I am unusual, that IS the point. I do not care for formats or traditional thought. Every interview of mine is different, just like a mood. A lot of you are meeting me for the first time. Don't compare me to what you would do or be. Be free.— rose mcgowan (@rosemcgowan) February 1, 2018
