In 2012, the star was hospitalized after a failed suicide attempt.

"For the past five years, he had been grappling with health issues that precluded his active pursuit of work," Daniel's former agents said of the actor, who also appeared in films 'O Brother, Where Art Thou?' and 'Super Troopers.'

"We remember him fondly for his easy-going professionalism and dry wit, both of which stood in stark contrast to the driven and near-maniacal roles he often performed with such energy and intensity. He was a joy to work with and we have missed that association since his semi-retirement to Cincinnati," his agents told 'People' magazine.

Our thoughts are with Daniel's family and friends during this difficult time.
