Aaron Johnson, Taylor Kitsch and Blake Lively's characters are among those introduced via the interrogation-themed videos.
Stone's drama centres on two pot growers (Johnson and Kitsch) who are forced to face off against a Mexican drug cartel when their mutual girlfriend (Blake Lively) is kidnapped.
In the first video, Lively's character Ophelia explains that both Ben (Johnson) and Chon (Kitsch) are her boyfriends.
Asked how she can live with two men, she answers: "How do some women not? I don't know. It's all I know."
Another pair of videos sees Ben and Chon being interrogated about how they make money.
In the last two videos, Salma Hayek and Benicio Del Toro are introduced as cartel leaders Elena and Lado.
