I’m not sure how much help he’s going to be, and even worse, I fear what Harley will do to him if he isn’t able to help the couple.
In the DCEU, Joker and Harley are still an item, but evidently at the start of this movie, Harley thinks their relationship needs some work, hence why she’s abducted Dr. Phil.
Of all the celebrity cameos that could have been revealed for a Joker/Harley movie, I definitely wasn’t expecting Phil McGraw, but let’s roll with it.
More importantly, I’m curious if Glenn Ficarra and John Requa would actually be successful in recruiting Dr. Phil for this cameo or if they’d have to create their own TV psychologist character to fill that role.
