The youngest of four children of a businessman father and a teacher mother, Ben Chaplin was born and raised in Windsor, England. An admittedly lazy student who harbored no desire to go to university, he found his calling as a teenager when he appeared in a play. Noticing in the biographies of actors in theater programs that nearly all attended some form of drama school, he enrolled at London's Guildhall School of Music and Drama, but by his second year it was clear he and the institution's program weren't a good fit. Asked to leave, he found work at theater companies and honed his craft.

In 1992, Chaplin landed his first break starring alongside James Purefoy and Jason Flemyng in "Bye Bye Baby" for Channel Four. He segued to the big screen in the Merchant Ivory drama "The Remains of the Day" (1993), playing a footman, and reteamed with the filmmakers who produced his breakthrough screen role as the socially inept Con Wainwright in "Feast of July" (1995). 1995 had proven something of a banner year for the actor. He garnered raves as Tom in a Sam Mendes-directed production of "The Glass Menagerie" on the London stage, and won the hearts of many as the oddball agoraphobe Matthew Malone in the British sitcom "Game On!"

Crossing the pond, director Michael Lehmann cast the full-browed actor as Brian, a photographer caught between two women, in "The Truth About Cats & Dogs", a distaff spin on "Cyrano De Bergerac. Displaying an easy charm and affable screen presence, Chaplin soon found himself in demand, although many of the parts were too similar to Brian. Eschewing the obvious, he stepped into the boots of Montgomery Clift essaying the fortune hunting Morris Townsend in a retelling of "Washington Square" (1997), co-starring Jennifer Jason Leigh. Despite their sterling performances, the film failed to generate much interest at the box office. His next film was even more of a risk, but a richly rewarding one for an actor. Cast as Private Bell in Terrence Malick's lyrical remake of "The Thin Red Line", Chaplin emerged as one of the film's key figures as his grunt wistfully recalls his times with his wife (Miranda Otto) as a means of coping with life on a battlefield. Despite his fine work, the actor found many overlooking his contribution to the film as reviewers concentrated on Malick's efforts.

One of the vagaries of the film business has to do with the time between when a project is lensed and when it finally reaches theaters. After numerous delays, "Lost Souls", which was filmed in 1998, finally hit theaters in fall 2000. Cast as a skeptical crime writer who is told he has been marked for Satanic possession by a woman who herself fought off the devil, Chaplin managed to maintain his dignity despite the inanity of the screenplay. He fared much better as a low-level bank clerk who gets more than he bargained for when he selects a Russian mail-order bride (played by Nicole Kidman) in "Birthday Girl" (2001). After unspooling at the Venice, London and Toronto Film Festivals and screening at the 2002 Sundance Film Festival, "Birthday Girl" opened to generally positive reviews. Chaplin next teamed with Sandra Bullock as her relatively inexperienced partner aiding in investigating a series of killings in "Murder By Numbers" (2002). He then co-starred with Michelle Yeoh in "The Touch" (lensed 2001-2002).
