Written by Alan Seymour, Dubbo residents will see the meaning of Anzac Day in a completely new form of ideologies.

Cast member, Don Bridges, a veteran of the Australian theatre industry, said he was humbled to be involved in the play, which was celebrating its 50th anniversary since first performed in Adelaide.

Witnessing the reception of Anzac Day in the 1960s firsthand, Bridges said there had been a strong "anti-war movement".

"We're a small cast of only five, but the characters are all critical to showing the play's meaning," Bridges said.

Taking to the stage as Wacka Dawson, a role he described as "a silent but interesting character", Bridges said he had taken a lot out of his own personal experiences of Anzac reception when studying the script.

Bridges' said The One Day of the Year focused on a father-son relationship between Alf Cook and his son, Hughie.

"There's a lot of conflict between Alf and Hughie," Bridges said.

"Their perception of how Anzac Day should be commemorated is very different."

Alf, who served in the First World War, operates an elevator and is able to feel important and recognised once a year, on Anzac Day.

Hughie, a university student, had a completely different perception of the day and doesn't understand why his father hits the drink hard on April 25.

Bridges said the tension on stage as the father and son challenge each other was "intense to say the least".

"Wacka served in the First World War with Alf's father and the second world war with Alf," he said.

Describing his character as "strong and silent", Bridges said his lines were few, but "when he talks, people listen, which is very rare for an actor".
