As events hurtle toward endgame in tonight's episode of Rebellion, actor Marcus Lamb has said that playing doomed rebel Padraig Pearse in the 1916 drama was a fascinating experience.

"Pearse was this odd combination of shyness and this explosive charisma when he wrote and gave these incredible speeches, like at the grave of O'Donovan Rossa," said the actor, who previously played Des O'Malley in RTÉ drama Charlie and who can also be seen in the upcoming film adaptation of The Secret Scripture.

Pearse famously had a bad squint in one of his eyes and Lamb wore a silicon over his right eye for the part. "He was a self-conscious man and always insisted on being photographed in profile," Lamb said.

Fellow Rebellion actor Ruairí Heading, who plays Fusilier McGarry, one of the many young Irishmen who signed up to the crown forces, said that he felt the series is covering an oft-overlooked aspect of the era.

"It's one of the sides we don't often see when we look back at the history of it," Heading, who also appeared in Irish comedy film Get Up and Go, said. "We're always taught about the rebels and in a way, the glory of the Rising but you forget that there was a lot of young Irish guys who fought for the British as well."
