Former California Governor Arnold Schwarzenegger has delayed all his future film projects, a statement from his office has confirmed.
The 63-year-old, who had planned to return to acting after launching a political career, is "focusing on personal matters", the statement said.
Schwarzenegger recently admitted he had fathered a child with a member of his household staff more than 10 years ago.
The former Terminator star and his wife Maria Shriver have separated.
The full statement said: "Governor Schwarzenegger is focusing on personal matters and is not willing to commit to any production schedules or timelines.
"This includes Cry Macho, the Terminator franchise and other projects under consideration.
"We will resume discussions when Governor Schwarzenegger decides."
Ms Shriver, who has moved out of the family home in Los Angeles, has been married to the former actor for 25 years.
They have four children between the ages of 14 and 21.
Schwarzenegger has maintained a high public profile and worked to revive his movie career since finishing a seven-year run as California governor in January.
Among the potential projects were plans for him to voice the central character in the animated TV series The Governator.
The show, which depicts Schwarzenegger as a devoted family man who lives a double life as a superhero, also halted production on Thursday.
