As the TV star dives into a brand-new challenge on I’m A Celebrity… Get Me Out of Here!, fans are being reminded of a chapter from her acting past that many have forgotten — and based on viewers’ reactions, there may be a very good reason it slipped through the cracks.

Back in 2012, model and television personality Kelly Brook appeared in the British comedy Keith Lemon: The Film, a big-screen spin-off of the popular ITV2 panel show Celebrity Juice. Despite the hype surrounding its release, the movie has since been described by online critics as “unfunny,” “juvenile,” and even “horrible.” According to The Guardian, the film was widely panned for its “relentless crudeness” and lack of coherent plot (The Guardian).

In the comedy, Brook plays a fictionalised version of herself and becomes the love interest of the chaotic, larger-than-life character Keith Lemon, portrayed by comedian Leigh Francis. The film attempted to capitalise on the success of Celebrity Juice, which frequently pulled in strong ratings during its peak years. As Radio Times noted at the time, producers hoped the character’s TV popularity would translate to cinema success — but viewers were left divided (Radio Times).

A Film Packed with Celebrity Cameos — but Not Much Critical Love

The movie leaned heavily into shock humour, risqué gags and cameo appearances. Alongside Brook, the cast included David Hasselhoff, Gary Barlow, Peter Andre, Emma Bunton, and even pop duo Jedward. However, the film’s central focus rested on Verne Troyer, who played Keith’s guardian angel, and Laura Aikman, portraying his long-suffering partner Rosie.

Despite the star-studded lineup, critics were far from impressed. One scathing Rotten Tomatoes review read:

“To be honest, it was the worst film ever. Keith Lemon is okay for TV but not for the big screen. Kelly Brook was D-list. It's not funny at all. Holly and Fearne should have had bigger parts. Overall, rubbish.”

Another viewer echoed the sentiment:

“To say this film is bad would be an understatement. The ‘jokes’ are so immature they make you uncomfortable. The story looks like it came from a child’s English class.”

The Independent described the film as “a chaotic collage of tired gags,” arguing that the humour felt outdated even upon release (The Independent). Meanwhile, BBC Culture criticised the film for “stretching a sketch-based character far beyond his natural limits” (BBC Culture).

The Plot: Fame, Fortune and Disaster

The story follows Keith Lemon as he faces a disastrous business failure in London, leading to tensions with his pregnant girlfriend Rosie. His luck suddenly changes when he invents a wildly successful new phone, turning him into an overnight millionaire.

With fame and fortune at his fingertips, Keith moves to Hollywood, embracing a lavish celebrity lifestyle. Soon, he begins dating the glamorous Kelly Brook — a subplot that played into Brook’s persona at the time as a sought-after model and TV figure.

However, Keith’s newfound success comes at a cost. He becomes indebted to the villainous Evil Steve, who ultimately kidnaps Rosie and forces Keith to step up as an unlikely hero.

Mixed Audience Reactions: Some Hate It, Some Love It

While critics were overwhelmingly negative, not all viewers agreed. Some Celebrity Juice fans genuinely enjoyed the movie for exactly what it aimed to be — loud, ridiculous and deeply unserious.

One fan wrote:

“Never seen Celebrity Juice before, but thought this film was freaking hilarious!”

Another added:

“A great and funny comedy full of everything you’d expect when you step into the world of Keith Lemon. If you like him, you’ll love the film. Worth every penny.”

This split in opinion reflects what BBC News later described as the “Marmite effect” of Leigh Francis’ comedy — viewers either love it wholeheartedly or cannot tolerate it at all (BBC News).

Looking Back as Kelly Brook Enters the Jungle

With Kelly Brook now taking on bush-tucker trials and jungle challenges on I’m A Celebrity, her role in Keith Lemon: The Film is resurfacing — sometimes humorously, sometimes critically. Despite the film’s reputation as one of her less successful ventures, Brook has since appeared in a range of films and TV projects, and has built a long-lasting career in British entertainment.

Whether viewers consider the 2012 movie a guilty pleasure or a regrettable misstep, one thing is certain: it remains a memorable — if controversial — moment in her filmography.
