Diactorism 

The phenomenon that occurs when you realize you've been conflating two or more different actors or actresses as a single person. Most common with young actors before they make it big or character actors.

Common examples:
Shia Labeouf and Topher Grace
Kurt Russell and Patrick Swayze
Rachel Bilson and Mila Kunis
Omar Epps and Mekhi Phifer and Sean Patrick Thomas

I had serious diactorism this morning when I realized Shia Labeouf wasn't on That 70s Show. Turns out Topher Grace is a different guy.

Doctorism 

The near-religious belief that the Doctor (Doctor Who) exists and does in fact save your life nearly every day. This belief arises from unexplained happy-coincidences, such as an unknown man catching a baby that fell 3 stories, or the oil from the 2009 spill disappearing. Subscribers to Doctorism are known as either Doctorites, Companions, or Neo-Whovians.

Doctorism at its best:
Ronny: "Hey, did you hear? That family that went missing a week ago turned up! No one knows how, and they don't really remember."

Joe: "It was the Doctor for sure! I knew he's real!"
