SYDNEY'S Belvoir theatre company has been forced to reinstate the final scene of Arthur Miller's famed Death of a Salesman after an anonymous tip-off to the US agent that handles the rights about changes made to the local production.

Following a sell-out and critically acclaimed season at its Surry Hills theatre earlier this year, Belvoir has been granted rights for a second season that starts next week at the Theatre Royal on condition it reinstates the play's final act, or Requiem.

Controversial changes ... Belvoir producton of Death of a Salesman, starring Colin Friels.

The director Simon Stone had cut the ending of Death of a Salesman - arguably the greatest play of the 20th century - without permission.

When the rights were first negotiated about 18 months ago with the New York agent ICM Partners there had been a ''mis-communication'' about the cut, Belvoir general manager, Brenna Hobson said.
