Ravil Isyanov, a Soviet-born American character actor, popularly known for his appearances in numerous films and TV shows, has passed away at the age of 59.

According to Deadline, the actor died on September 29 at his Los Angeles home after a long illness. The outlet did not specify his medical condition.

His manager, Fredrick Levy, released a statement to Entertainment Weekly saying, "Even while battling this awful disease, Ravil remained brave and resilient, bringing his best to the set and working up to the very end, he will be dearly missed."

Isyanov spent his early days in Voskresensk, Russia. At a young age, he already realized that performing arts was his passion. He studied directing in the Perm Institue of Culture after graduating from high school in 1980. However, his education was abruptly cut two years later as he left to complete two-year mandatory military service in the Soviet Air Force.

Once he got back, he was able to work at the Khabarovsk Theatre for two seasons. He then continued his studies by getting into the acting program at the renowned Moscow Arts Theatre in 1986.

He became close friends with Andrei Panin at school, a famous Russian actor who passed away in 2013.

Isyanov was able to land a small role in the 1990 American film "The Russia House," which stars Sean Connery and Michelle Pfeiffer. The movie was filmed in Moscow.
