The giant is played by Buddy Baer, who also played Donald in the first half of the movie. Abbott and Costello's comedic skills are on full display, as they manage to outwit the giant and survive the fantastical adventure unscathed. Fans of Abbott and Costello's classic routines will be pleased to know that this beloved duo's famous "Who's on first?" shtick is also featured in the film.

The second half of the movie, Africa Screams, is a hilarious parody of jungle adventure films that were popular at the time. Abbott and Costello play Buzz Johnson and Stanley Livington, respectively, two bumbling book salesmen who get conned into traveling to Africa in search of treasure.

Once they arrive in Africa, they become lost in the jungle and are chased by a variety of wild animals, including a lion, a gorilla, and a rhinoceros. Interestingly, the film features real-life African wildlife, which lends an air of authenticity to the otherwise zany proceedings.

In Africa Screams, Abbott and Costello once again showcase their trademark comedic chemistry, with Costello playing the hapless, anxiety-ridden Stanley and Abbott playing the more level-headed Buzz. The ing cast includes Evelyn Ankers, a familiar face from Universal's classic horror movies, and Joe Besser, who would go on to become a regular on The Three Stooges TV series.

The movie's director, Charles Barton, worked extensively with Abbott and Costello throughout their career, directing most of their films. His direction helps to keep the pace lively and the comedic timing sharp. The movie also features an energetic score by Walter Schumann, who contributed to the music of many other films, including The Night of the Hunter.

Overall, Abbott & Costello Double Feature - Jack and the Beanstalk & Africa Screams is a wonderful trip down memory lane for fans of classic comedy. The duo's ability to play off each other is unmatched, and their hilarious antics will continue to entertain audiences for generations to come. This movie is a must-watch for fans of Abbott and Costello, and anyone who enjoys a good laugh.
