Numb3rs cast and characters

One of those faces that regularly popped up in memorable cameos in film and TV, David finally got the chance to stretch himself with the integral role of Charlie in this popular US crime drama.

The New York born actor has taken on the role of the maths whiz with relish, his ability to produce a different take on a crime helping his brother solve a myriad of pesky LA cases.

One of the small screen's most endearing stars, Rob warmed the hearts of tube followers around the world with his starring turn as New York-turned-Alaskan doctor Joel Fleischman in Northen Exposure back in the 90s.

The role saw him nominated for two Emmys and three Golden Globes, before Robert Redford handed him a big part in Quiz Show opposite Ralph Fiennes. Since then he has racked up numerous film and TV roles before landing the top gig as the FBI Special Agent older brother of Charlie.

Having lit up the goggle box as wise cracking Alex Rieger in seminal 70s sitcom Taxi, Judd knows a thing or two about being part of a smash hit TV programme. The role won him two Emmys as Outstanding Actor in a Comedy Series.

Not only that, he won a Golden Globe for his starring role in the comedy Dear John, while Oscar also took notice of him with a Best Supporting Actor nom in Robert Redford's Best Picture Winner Ordinary People. The Bronx native plays the father of Don and Charlie.

The daughter of Indian and German parents was born in Malibu and look destined for TV stardom after finishing her studies in New York. She launched her career with bit part roles before getting a good run on the hit series 24.

She parlayed that into meaty gigs in the film The House of Sand and Fog and The O.C. before the Num3rs team let her loose as a mathematician at CalSci and FBI consultant who is currently dating Charlie.

Megan is an FBI behavioral specialist, who is romantically involved with Larry Fleinhardt on the show, something that shouldn't come as a stretch for the actress who made her name on Roswell, Like Family and critical hit Rescue Me.

Her character is considering a career change to counsel troubled young women, a plot turn that Diane can relate to after she produced a documentary about the lives of several children who escaped from the Children of God cult.

The Bronx native plays one of the FBI Agents who regularly helps out on the cases from the first season right through to the one currently airing. Bizarrely, Alimi got his big break playing a character on Sabrina, the Teenage Witch.

He moved into more adult fare with his turn as Herbal Thought on Dark Angel that unleashed Jessica Alba onto the world in all her glory. One of the ever presents, David is one of the lynchpins of the successful Stateside show.
