Screenrant stresses this is unofficial word from a source who claims they were given explanation of the plot by one of the show’s stars.
Ron Howard is making a movie about the Bluths using an A-List cast. But Dr. Tobias plays himself because nobody wants to play him in the movie. The Bluths decide to make their own movie in contention with Ron Howard’s.
Screenrant also goes on to tease that an official announcement about the film may be coming in the next few weeks.
