The decade of the seventies marked a period when British audiences developed a fondness for risqué humor, almost feeling entitled to enjoy it. While the quality was often unremarkable—the "Carry On" films would delve into crude jokes in pursuit of laughter, and the "Confessions Of" series wasn't particularly strong—many moviegoers were content as long as actors like Robin Askwith appeared amidst scantily clad women, exposed backsides, and suggestive remarks. “On the Buses” was a very popular television program in the UK, running for seven seasons from 1969 to 1973. Like many British sitcoms of that era, it transitioned to the big screen with three theatrical releases, among which "Holiday on the Buses" stood out as the final installment—and, thankfully for some, signaled an end to such ventures. Watching it today reveals a film that feels dated, with its creators visibly struggling to maintain the bawdy formula, forcing beloved characters into increasingly absurd scenarios in hopes of eliciting laughs. Though there are still some enjoyable moments for fans of the original series, those unfamiliar with it will likely only muster a slight chuckle. It’s difficult to now accept that actors like Stan Harper (Reg Varney) and Jack Harper (Bob Grant) were once considered attractive enough to be womanizers and have easy access to romantic encounters! That's what audiences in the seventies were expected to believe, though. Just because there's snow on the roof doesn't mean the fire has gone out down below. The story finds Stan, the bus driver, and Jack, the conductor, working at a Pontins Holiday Camp—a very British concept from the 70s—and attempting to find romantic opportunities at every turn. Stan’s sexually frustrated sister, Olive (Anna Karen), also participates, desiring affection from her husband Arthur! (Michael Robbins). Even widowed Ma Butler (Doris Hare) is open to a bit of romance, courtesy of Wilfrid Brambell, the king of lecherous men. Predictably, nemesis Inspector Cyril ‘Blakey’ Blake (Stephen Lewis) appears to provide the mischievous duo with opportunities for slapstick comedy, and even he finds himself with a romantic interest in the holiday camp Nurse played by Kate Williams. There are some amusing scenes, such as a sequence set at a swimming pool, or Arthur Mullard attempting to dance—a genuinely funny moment if you know the actor's style—and even Brambell’s usual suggestive routine can be entertaining at times. Ultimately, however, it’s a film intended for fans only, and even they will have to overlook its careless shortcomings. 5/10
