Question: For which screenplay did Bill Walsh contribute he shared Academy Award nominations for Best Picture with Walt Disney?
Context: Tom Martinez (February 21, 1946 – February 21, 2012) was an American football coach.  He coached at the College of San Mateo until 2005, when he retired due to health concerns.  He coached at the College of San Mateo after Bill Walsh and John Madden.  The College of San Mateo Football program traditionally has a very high ranking team and draws players from all over the country.  It is interesting to note that NFL Alumni John Madden, of the Oakland Raiders & Bill Walsh, of the SF 49ers, both played & coached at the College of San Mateo early in their careers.  Bill Walsh was claimed to be the best NFL Coach ever and later retired from the 49ers to become the athletic director at Stanford University.  (Ref.  the College of San Mateo Football & Sports Hall of Fame websites for info on Martinez, Walsh, Madden & others).  Prior to the passings of Tom Martinez, he was inducted into the College of San Mateo Sports Hall of Fame.  Many of his former College of San Mateo Football Players remember Tom as taking a Military Drill Sergeant type approach to Coaching at the College level.  Tom had a passion for conducted private coaching sessions with quarterbacks of all ages & from all around the country. 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. This is a list of presenters of Best Picture Academy Award.  Each year, the Academy Award for Best Picture is presented by one or more artists on behalf of the Academy of Motion Picture Arts and Sciences.  Since 1973, Best Picture is the final award presented during the annual ceremonies, as this award represents a culmination of all factors that contribute to cinematic excellence.  Past presenters have included noted producers, directors, actors, and actresses.  In recent ceremonies, presenters of Best Picture have tended to be previous Academy Award winners themselves.  The individual who has presented the most times is Jack Nicholson (eight times), followed by Audrey Hepburn (four times).
