Jessica Simpson is the new personification of the traditional Hollywood dumb blonde. She has achieved some success as a singer, as a reality TV star with ex-hubby Nick Lachey in “Newlyweds,” and scored a movie hit in “The Dukes of Hazzard.” She was seen doing the bimbo role in last year’s “Blonde Ambition,” which was not released locally. She’s now back in the new sexy comedy, “Major Movie Star,” which is also titled as “Private Valentine: Blonde & Dangerous.”

During her heydays in the ’70s, Goldie Hawn had already done a movie like this, “Private Benjamin.” Jessica plays a spoiled actress, Megan Valentine. She has a retinue of stylists, agents, fans and parasitic family leeches following her. She’s got fame and fortune but she soon discovers that her wealth has been stolen by a sleazy accountant called Cousin Barry and her boring blonde boyfriend who she thought was traveling somewhere turned out to be in bed with her gay manager. With her last movie being a flop, she now wants to play the plum role in a new movie that is about the military, but the producer told her that she is not fit for the said role.

Terribly depressed, she gets drunk and regains consciousness in the army recruitment center. She decides to take a break from showbiz and joins the Marines to make the producer take notice of her. She finds the Marine uniform cute and also welcomes the change of scenery at the boot camp where she is sent to train. She is placed under the strict guidance of Sgt. Morle (Vivica A. Fox) and soon, Megan realizes her mistake. She’s not accorded the usual star treatment given to her. Intimidated by the harsh conditions in the camp and the overbearing discipline imposed on her, she is also made to do all tasks assigned to her without any doubles.

The fall from a high-class glamorous job to low-class camp recruit takes its toll on her. For a while, she thinks of quitting, but she gets to bond with the other recruits, including Olesya Rulin from “High School Musical” and Keiko Agena from “Gilmore Girls.” They help motivate her to exert more effort in her desire to prove herself to those who doubt her abilities to pass basic training. She manages to get them some chocolate bars that they eat in a manner like they’re performing oral sex on it.

Megan finds out that her cruel drill sergeant used to star in sleazy B horror flicks. She manages to show one of the sergeant’s old movies and she is humbled in front of everyone. With the help of her manager, Megan is released from the army and she realized that her life before the army was empty and meaningless. She fires all those who exploit her and returns to camp to finish what she started. They engage in field exercise and she manages to save the day for her team, making her earn the respect of her fellow cadets.

Those who like Jessica will no doubt lap up all her uproariously dumb shenanigans in this ditzy comedy. She has a gracious and pleasant screen presence that makes you forget that the film’s dopey material has been done before in other fish out of water Army recruit flicks. The usual elements in this kind of movie are all here, the iron-fisted sergeant (Fox), the spiteful private (Cheri Oteri) who joined the army as she had a failed marriage, the punishing initiation rites that involve hazing, how the heroine earns the respect of others, and the action-filled war games in the climax where Private Valentine emerges as a hero.

Directed by horror filmmaker Steve Miner (“Halloween H20,” “Lake Placid”), “Major Movie Star” will truly be horrifying for those looking for serious film fare. But those who just want to have a good laugh will no doubt enjoy it. It also makes fun of the showbiz milieu as populated by gays. Those who’ll watch the movie mainly for a glimpse of Jessica’s sexiness will also not be disappointed as there are many scenes that exploit her shapely figure, including one where she does push-ups with plenty of breast shots. Jessica now competes with Anna Faris for the Dumb Blonde title as Anna also played the same role in “The House Bunny.”
