Love Happy (1949): The Marx Brothers' Forgotten Finale Featuring Marilyn Monroe

Love Happy (1949) is the final feature film starring all three Marx Brothers on screen together. It's also the picture that gave a 23-year-old Marilyn Monroe her first speaking role in a major-studio production — a 38-second walk-on as a sultry client who hires Detective Sam Grunion (Groucho) to investigate diamond smuggling. The scene lasts under a minute. Within three years she'd be Hollywood's biggest star.

How the Marx Brothers ended up here

By 1949 the Marx Brothers had been on screen for nearly twenty years. Their MGM peak with A Night at the Opera (1935) and A Day at the Races (1937) was a full decade behind them. Their subsequent United Artists pictures had been progressively weaker. Love Happy was conceived as a Harpo solo vehicle — Chico Marx appears in the picture but Groucho Marx only books in for short detective-narrator framing scenes. It was the brothers' last collaborative outing on film.

The Marilyn Monroe moment

Monroe had been under contract at 20th Century-Fox since 1946 but had received only bit parts. Producer Lester Cowan saw her in a publicity reel and cast her for the brief Grunion-client scene. She walks toward the camera, says "Some men are following me," and exits with a famous over-the-shoulder glance. Groucho's reaction shot is the punchline. Monroe was paid $100 for the day.

The picture itself

The plot involves a stolen diamond necklace hidden inside a sardine can that ends up backstage at a low-budget musical theater Harpo is hired to help. Vera-Ellen leads the romantic subplot. The picture's signature setpiece — Harpo climbing across an animated rooftop covered in neon advertising signs — was largely shot for product-placement money to offset the production's miniscule budget.

The public-domain path

Love Happy fell into the public domain through copyright-renewal lapses by the original production company. The picture circulates freely. Its 85-minute runtime is brief enough to recommend even to viewers who aren't already Marx Brothers completists. The Monroe scene appears roughly seven minutes into the picture.

Where it fits in the Marx canon

This isn't a great Marx Brothers picture — even by the standards of their late period. But it's the last time all three appeared together in features, and Monroe's appearance has made it a permanent curiosity-piece. For Marx Brothers completists and Monroe historians, it's essential. For everyone else, the seven-minute Monroe sequence alone is worth the time investment.
