Without trying I've spotted several Scientologists on TV and in movies in just the last week.
It started with an old episode of 
Stargate SG-1
 (what a superb show) starring 
Corin Nemec as "Jonas Quinn" then came the movie 
Flightplan
 co-starring 
Erika Christensen (an edge of your seat thriller starring the brilliant Jody Foster), followed by an episode of 
Law & Order: Criminal Intent
, guest starring 
Elizabeth Moss and another Law and Order: CI guest starring 
Geoffrey Lewis. Then to top it all off Elizabeth Moss was featured in Entertainment Weekly in her role as "Peggy Olsen" in the award winning series 
Mad Men
.
All that in just the last week and I don't even watch a lot of TV and movies.
A culture is only as great as its dreams, and its dreams are dreamed by artists. — Scientology founder L. Ron Hubbard
