Premise: George Tzavellas, also rendered Giorgos Tzavellas, Yiorgos Tzavellas, or Yorgos Javellas (Greek: Γιώργος Τζαβέλλας , 1916, Athens – October 18, 1976), was a Greek film director, screenwriter, and playwright. His filmmaking was particularly influential, with critic Georges Sadoul considering him "one of the three major postwar Greek directors" (along with Michael Cacoyannis and Nikos Koundouros).
Hypothesis: Yorgos Javellas wrote plays and movie scripts in Athens.
