The campaign, created by MCBD with media buying by the7Stars and planning by Naked, is presented from the perspective of someone suffering from a mental illness and aims to make people question their own prejudices without pointing fingers.
The programme is being run by mental health charities Mental Health Media, Mind and Rethink. It is being funded by £16m from the Big Lottery Fund and £2m from Comic Relief.
The TV ad presents the issue in a narrative, while the press ads feature quotes and case studies from a mixture of celebrities and members of the public, who have experienced mental health problems.
The Stephen Fry ad reads, ‘1 in 4 people, like me, have a mental health problem. Many more people have a problem with that'.
Outdoor ads on tube cards and escalator panels will present the facts and myths about mental health problems.
The TV ad first airs during Coronation Street on 21 January.
