After a long absence, Ali G returns to a world he finds transformed by Covid, wars and Ed Sheeran – and his long-suffering girlfriend Julie is expecting his baby. Following on from Ali G Indahouse (2002), the film mixes scripted storytelling with hidden-camera encounters in the style of Borat and Da Ali G Show, as Baron Cohen takes the character out among unsuspecting members of the public. Ali G's preparations for parenthood take him from doctors' appointments to a birthing class, where he cheerfully announces his plan to be an absent father, alongside interviews with real-life figures who have no idea they are being set up.

Sacha Baron Cohen's first feature as director. The film was shot in secret, with Baron Cohen spotted filming in character at an Oxfordshire zoo in July 2025. Ali G first appeared on Channel 4's The 11 O'Clock Show in the late 1990s.
