Ballots for the 19th annual Screen Actors Guild Awards nominations will be mailed Wednesday to the film and TV nominating committees.Nominations will be chosen by two separate film and television nominating panels, each comprised of 2,100 SAG-AFTRA members who were randomly selected in the spring. Votes, which may be cast online or through a mailed paper ballot, must be received by Dec. 10. Nominations will be announced two days later at the Pacific Design Center in West Hollywood, and the awards ceremonies will take place Jan. 27 at the Los Angeles Shrine Exposition Center. Although SAG and AFTRA members voted in March to merge the unions into SAG-AFTRA, the awards show will retain the SAG moniker for the 19th iteration. That could change as the current TV contracts with TBS and TNT run through the January show but don’t cover the 20th show in 2014.
