The new set comprises The Cocoanuts, Room Service, Love Happy and A Girl In Every Port.
The Cocoanuts was the first Marx Brothers movie ever, an adaptation of their hugely successful Broadway stage show. Ii was also the first musical comedy captured on film.
1949’s Love Happy was the last film the brothers headlined and features a cameo from Marilyn Monroe when she was a 23-year-old aspiring starlet
In Room Service, Groucho plays a theatrical producer holed up in a hotel room; he doesn't have a cent but he does have a sure-fire Broadway hit, while A Girl In Every Port was Groucho's second solo outing for RKO, in which he played a scheming sailor.
The new £34.99 set is a follow-up to Universal Pictures’ first best-selling Marx Brothers Collection of Animal Crackers, Monkey Business, Horse Feathers and Duck Soup.
Also out on Monday is an eight-disc box set combining all the titles in both releases, priced £49.99.
But we have three sets of the eight-disc collection and three of the new four-film set to give away to Chortle readers.
