Allelujiah is a warm and deeply moving tale of old age – directed by Richard Eyre.

The impending closure of a geriatric ward at a small Yorkshire hospital sparks an uprising from the local community, who invite a news crew to film preparations for a concert honoring the hospital’s most eminent nurse.

Derek Jacobi and Russell Tovey also star in the large cast of Richard Eyre’s film adaptation of Alan Bennett’s recent play about the NHS, which premiered in Toronto.
