SAG Probing Motion Capture Work
Guild will host Dec. 3 discussion of technique and its impact on actors.
With motion capture becoming increasingly popular production technique, the Screen Actors Guild is investigating how actors perform the work -- a signal the issue may emerge as a factor in next year's contract negotiations.
The guild this week invited members and non-members who do the work to a Dec. 3 session at the guild's Hollywood headquarters to discuss the impact of performance capture.
