[15][16] The play itself nearly caused a riot; fourteen cast members walked out on opening night due to shoddy production values.

The notoriety of City of Angels coupled with newspapers running photos of Haynes in it may have led to her receiving uncredited parts in two movies, Knock on Any Door and We Were Strangers, filmed in 1948 for release the next year.

Performed at Stanford's Memorial Theatre during July 1949, the production starred Jessica Tandy and Akim Tamiroff, with Jeanne Bates, Feodor Chaliapin, Milton Parsons and Haynes as the supporting professionals.

[37] Based on James Michener's short story Mr. Morgan set on the fictional island of Matareva, the film was to be shot on location in the South Pacific.

[41] She would spend a month in the small village of Matautu, Lefaga before the rest of the Hollywood cast and crew arrived, to soak up local customs, speech patterns, and ways of moving.

She wrote occasional letters back home from which her mother fed snippets to the local papers,[43] and even spoke with her parents via short-wave radio courtesy of a neighboring ham.

[fn 2][45] Location filming completed in late September 1952, and the Hollywood cast flew back to Los Angeles by the end of the month.

[47] Howard McClay wrote Haynes "brings a warm, almost childlike quality to a role that could easily have been overdone in less understanding hands".

[50] Y. Frank Freeman issued a statement for the Association of Motion Picture Producers denouncing "salacious" photos of females and warning they would not lead to success.

Haynes was then said to be set for a 3-D remake of Golden Boy called Strong Arm, which would co-star Broderick Crawford and John Derek, but the project was abandoned.

Sent out on a tour to the East Coast to promote Return to Paradise for Aspen Productions, Haynes alarmed her new bosses at Columbia with her frankness in interviews: [The Samoans] can't pronounce their R's...

[fn 8][73] She is credited on IMDb with a 1955 Franco-Italian film called Tua per la vita, for which she was either a very minor actor or possibly provided English dialogue.

During December 1955 Jon Hall cast Haynes in two half hour pilot episodes for a new series called Knight of the South Seas, in which he would star.

[92] During this year she also made some pilot episodes for a new MGM series called Provost Marshall, which co-starred Ralph Meeker and Mari Blanchard.

She appeared in Look Back in Anger at the Laguna Beach Playhouse, with Don Harron, Marcia Henderson, Michael Gibson, and Nelson Welch.

Her final acting roles on television were all minor bits, including a TV movie The Rules of Marriage and the series Falcon Crest in 1982, and episodes of Knots Landing and Knight Rider in 1986.

[107] Columnist Lee Berg described her in an interview: "Roberta is a tense, enigmatic young lady, who conceals her drive behind a placid exterior and a gentle voice that is almost a whisper".
