The On Cinema Family is the colloquial term for the community surrounding the On Cinema series. The term was coined by Gregg Turkington in Podcast Episode 8: "Star Trek II: The Wrath of Khan".

Members of the On Cinema Family usually self-describe themselves as Timheads or Greggheads, to show their favorite host/guest is Tim or Gregg. Other similar names are “Markhead,” “Joehead,” or “Unityhead,” though the latter is often looked down upon by other members of the On Cinema Family.
