Question: What film did Anthony Powell take part in that was nominated for six Academy Awards?

Context paragraphs:
Agents and Patients: Agents and Patients is the fourth novel by the English writer Anthony Powell.  It combines two of the aspects of 1930s life, film and psychoanalysis.  In what Powell himself has acknowledged is a "roman a clef" of sorts (Anthony Powell, "Journals 1987-1989", 121), a comically critical eye is cast across "entre deux guerres" society and its often self-indulgent, usually unsatisfied quest for contentment.

Venusberg (novel): Venusberg is the second novel by the English writer Anthony Powell.  Published in 1932, it is set in an unidentified Baltic country which draws clearly on Powell's experiences in Finland and Estonia.  Some see the novel as part of the Ruritanian tradition (cf. "The Prisoner of Zenda"), perhaps a modernist pastiche of the form.

Picnic (1955 film): Picnic is a 1955 American Technicolor romantic comedy-drama film filmed in Cinemascope.

"Picnic" was nominated for six Academy Awards and won two.

Tess (film): Tess is a 1979 drama film directed by Roman Polanski, an adaptation of Thomas Hardy's 1891 novel "Tess of the d'Urbervilles".

Waldon O. Watson: Waldon O. Watson (January 20, 1907 – August 15, 1986) was an American sound engineer.  He was nominated for six Academy Awards in the category Sound Recording.  He worked on nearly 150 films between 1948 and 1973.
