More information about David Tennant's character in the new Channel 4 comedy Hang Ups has been revealed by the series' star and co-writer Stephen Mangan.

David will take on the role of Martin Lamb, an "eerie" cloakroom attendant and speaking to yesterday's Sunday Mail, Stephen disclosed a little more about what we can expect from the role:

"He  was given this character - this cloakroom attendant who does not like to talk with people. He was asked to work as a head waiter in a chic restaurant in London, but he can't cope. Everything else was improvisation, and David came up with such a terrific dark character who can't talk to people, but likes to take their hair from their clothes and touch their things. He's a real pervert."

Hang Ups is an unconventional comedy about an unconventional therapist trying to keep his unconventional life, and patients, from falling apart. Stephen stars as Dr. Richard Pitt, a therapist with a chequered professional career, who finds himself at a crossroads in life – a crossroads precipitated by the startling realisation that his life appears to be falling apart at the seams….

After the collapse of his previous group therapy practice, Richard is no longer able to conduct the traditional 50-minute sessions most therapists have with their patients. Instead, he’s developed a new form of therapy –weekly quick-fire sessions with his patients which take place online, through a webcam. The few patients on his list present a hilarious and outrageous catalogue of neuroses, phobias, issues, anxieties and psychopathies, but even these short sessions, where he’s confronted by everything from the sublime to the ridiculous, are not his greatest challenge... His patience and temperament are stretched to their limit by the daily interruptions of a demanding extended family, errant teenagers and his own trouble-filled past...

As well as David Tennant, the all star cast of clients and associates will include Richard E. Grant, Jessica Hynes, Katherine Parkinson, Karl Theobald, Arsher Ali, Celia Imrie and Paul Ritter.

Hang Ups will air on Channel 4 this summer.
