In this third remake of legendary Japanese director Akira Kurosawa's hugely influential The Seven Samurai, the seven gunslingers (George Kennedy, Michael Ansara, Joe Don Baker, Bernie Casey, Monte Markham, Fernando Rey and Reni Santoni) liberate Mexican political prisoners, train them as fighters and assist them in a desperate attack on a Mexican fortress in an attempt to free a revolutionary leader.
Unfortunately the movie Guns of the Magnificent Seven is not yet available on HBO Max.
