All other planned screenings cannot go ahead either.
Dunamaise Arts Centre has been forced to cancel the world premiere of a new Laois film.
An equipment breakdown means the first screening of Lost Hearts cannot go ahead as planned tonight.
A spokesperson for the Portlaoise arts centre says work is underway to repair the faulty projector.
It means all other planned screenings cannot go ahead on the advertised dates.
Alternative dates will be arranged and announced as soon as possible.
A stream-at-home option is available for Lost Hearts.
Film fans can click on dunamaise.ie to watch the beguiling film, which is based on a book by M.R. James, first published in 1895, which was shot at Roundwood House during the pandemic.
Ticket-holders are being offered a ticket for the new date, full refunds and/or offer a streaming online ticket in the case of Lost Hearts instead.
