Film director Jim Sheridan has become the latest celebrity to back the campaign for a Yes vote in the referendum on the Belfast Agreement.
He joined Ms Brid Rodgers of the SDLP in Belfast yesterday, to highlight the benefits a political settlement would bring to the film industry in the North.
Quoting from James Joyce's Ulysses, when Molly Bloom says "Yes, Yes, Yes", Mr Sheridan said he thought it was "about time we started saying Yes in Ireland generally".
With his production company, which is getting finance from Hollywood, he hoped to be able to make four or five films a year, and he said these could be set in any part of Ireland.
He believed there was more potential in the film industry in the North than in the South because of funding from the British lottery, the BBC and Channel Four.
Mr Sheridan has made two films relating to the North - In The Name of the Father, based on the story of the wrongful convictions of the Guildford Four; and The Boxer, on the problems faced by a republican prisoner on his release from jail.
He said he did not understand criticisms of the films as being sympathetic to republicanism. "They were sympathetic to the human race," he said.
Ms Rodgers said a Yes vote would unlock the potential of the North as a film location.
Between January 1995 and June 1996, 74 films were made in the South. In the same period, five films were made in the North, she said.
The SDLP would look for a degree of fiscal flexibility for the new assembly to allow it to introduce tax incentives for the film industry similar to those in the South, Ms Rodgers added.
