  • Robert Downey Jr. and Anthony Michael Hall are developing a TV series called "Singularity."
  • Hall told Business Insider that Downey Jr. plans to direct the pilot episode, which would mark the Oscar-winner's directorial debut.
  • Hall said the series had to be revised due to similarities with "Succession."

Anthony Michael Hall and Robert Downey Jr.'s friendship goes back to the mid-1980s when the two met on the set of the John Hughes classic "Weird Science" and soon after were cast members on "Saturday Night Live."

Though their career trajectories diverged — Hall went from '80s teen idol to character actor, Downey Jr. from unknown to "Iron Man" — the two have remained close friends. In fact, Hall is the godfather of Downey Jr.'s son.

Now, the old friends are in development on a TV series that would mark Downey Jr.'s directorial debut.
