During this time he also wrote and performed comedy
sketches for his station as well as Wisconsin Public Radio and appeared
on stage as a performer in musicals, comedies and dramas.
He continued to do theater after moving to Los Angeles to work
in film and TV. Favorite stage roles include Tevye in "Fiddler
on the Roof" and Pseudolus in "A Funny Thing Happened
on the Way to the Forum."
During his many years in L.A., Mark appeared in commercials,
voiced animated cartoons and worked for CBS, Paramount, Universal,
Disney and others.
Beginning in
1997, Mark started using his background in film production
to help inform people about Scientology's harmful practices.
In 1999,
Mark created his own website
XENU TV which features streaming video about Scientology.
He later joined with Bob Minton and Stacy Brooks at the Lisa McPherson
Trust and produced videos for LMT Media while continuing to work
on his own documentary about Scientology.
During this
period, Mark was in Chicago filming an interview with two dentists
who were trying to obtain a large refund from Scientology. To
disrupt the interview, Scientology hired off duty police officers
who arrested Mark for trespassing even though he was on a public
sidewalk. More than a year later, Mark was acquitted of all charges.

One week
after his arrest, Mark was assisting a German film crew as they
shot a documentary about Scientology in Clearwater, Florida. While
videotaping, Mark was attacked by a man who struck
his camera with a hammer. The man was ultimately arrested
and sent to jail on unrelated charges which were uncovered during
the investigation of the hammer attack.
Currently, Mark
works on the LMT website and is in charge of LMT Media. He continues
to cover Scientology, interviewing those affected by it and documenting
the behavior of Scientology's Office of Special Affairs.
