There are 2 actors playing Robotman: Brendan Fraser the voice and Riley Shanahan plays the body on screen.
Rita wears a red and white outfit in the final scenes in Cloverton. These colors are reminiscent of the team uniform her character wears in the 1963 comic series.
In Titans 1x04, Bruno Bichir played Prof Niles Coulder / The Chief. However, in Doom Patrol's own series Timothy Dalton took over the role.
Doom Patrol was introduced in Titans episode 4 of season 1.
At one point Robotman (voiced by Brendan Fraser) is wearing a Motörhead shirt. Not only did the band provide music for the movie Airheads (1994), which stars Brendan Fraser, but Motörhead singer/bassist, Lemmy Kilmister, also had a cameo in it.
