One of my astute film students has noticed that in a production still of CITIZEN KANE in our text (Film Art, Bordwell& Thompson, p. 15), Orson Welles is directing from a wheelchair. She (and I) ask why? Was it simply to reduce fatigue, or was he injured at some point during production (obviously when he wasn't acting himself!). We'd appreciate info. Mary McComb Asst.
