Question: What American actor who appeared in five films over a period of six years, all of which were nominated for the Academy Award for Best Picture, was part of the company  co-founded by David Wheeler and Naomi Thornton in 1963?

 He appeared in five films over a period of six years, all of which were nominated for the Academy Award for Best Picture: "The Godfather", "The Conversation", "The Godfather Part II", "Dog Day Afternoon", and "The Deer Hunter." John Holland Cazale ( ; ] ; August 12, 1935 – March 13, 1978) was an American actor.  He appeared in archival footage in "The Godfather Part III", also nominated for Best Picture, making him the only actor to have this multi-film distinction.  From his start as a theater actor, he became one of Hollywood's premier character actors, starting with his role as the doomed, weak-minded Fredo Corleone opposite longtime friend Al Pacino in Francis Ford Coppola's film "The Godfather" and its 1974 sequel.  Cazale chose to continue acting despite being diagnosed with lung cancer.  He died in New York City on March 13, 1978, shortly after completing his role in "The Deer Hunter". <SEP> The Academy Award for Best Film Editing is one of the annual awards of the Academy of Motion Picture Arts and Sciences (AMPAS).  Nominations for this award are closely correlated with the Academy Award for Best Picture.  For 33 consecutive years, 1981 to 2013, every Best Picture winner had also been nominated for the Film Editing Oscar, and about two thirds of the Best Picture winners have also won for Film Editing.  Only the principal, "above the line" editor(s) as listed in the film's credits are named on the award; additional editors, supervising editors, etc. are not currently eligible.  The nominations for this Academy Award are determined by a ballot of the voting members of the Editing Branch of the Academy; there were 220 members of the Editing Branch in 2012.  The members may vote for up to five of the eligible films in the order of their preference; the five films with the largest vote totals are selected as nominees.  The Academy Award itself is selected from the nominated films by a subsequent ballot of all active and life members of the Academy.  This process is essentially the reverse of that of the British Academy of Film and Television Arts (BAFTA); nominations for the BAFTA Award for Best Editing are done by a general ballot of Academy voters, and the winner is selected by members of the editing chapter. <SEP> Theater Company of Boston (TCB) was co-founded by David Wheeler and Naomi Thornton in 1963.
