Rudi Bach joined the film business very early where he remained true to his role type from the stage. He normally shot funny movies as a director and often took part in it as an actor too.
He is considered as discoverer of actress Lissy Arna.
He began his acting career at small theaters in 1903 before he managed the leap to the "Theater in der Josefstadt" in Vienna. Later followed engagements in Austria and Germany where he often played funny roles.
The track of Rudi Bach - who also used the pseudonym Idur Rivus - was finally lost. His year of death is not known until now.
