The actors who provide the voice-overs for video game characters are considering striking over pay and conditions.
The union that represents them wants better protection and pay for roles that cause "voice stress" such as repeated shouting.
It also wants a clearer definition between the roles of voice actors and those who are involved in motion capture.
Members are due to vote next month.
The Screen Actors Guild - American Federation of Television and Radio Artists (Sag-Afrta) said that, if more 75% of members agree, then all union members working on video games will go on strike.
It wants actors to get stunt pay for vocally stressful recording sessions and for such sessions to be restricted to two hours.
It is also calling for performance bonuses each time a game sells two million copies...
