 DATE: When in the Coconut Grove, an assistant tells Hughes that all  the color cameras in Hollywood are being loaned to Cecil B. DeMille  at Paramount so he cant have additional cameras for "Hells  Angels". DeMille left Paramount in 1925 to establish his own studio  where he remained until 1928 when he joined MGM. He didnt return to  Paramount until 1932 for "Sign of the Cross". The color cameras  referenced in "Aviator" would have been for the color sequences in  "King of Kings" a 1927 film made by DeMille for Pathe
