Cinematographer John Bailey, producer Gale Anne Hurd, effects expert John Knoll and editor Michael Tronick are joining the science and technology council of the Academy Of Motion Picture Arts And Sciences.

The influx raises the council’s 2014-15 membership to 25.

The council was established in 2003 by the Academy’s board of governors to exchange information, promote cooperation among technological interests within the industry and preserve the history of science and technology of film.
