Liam Neeson is nothing if not convincing.

The Irish actor appeared in an appeal on behalf of the Northern Ireland Children's Hospice, ahead of their annual holiday fundraising drive.

Despite being in his jolly Christmas sweater, it's difficult to hear the 67-year-old's instantly recognizable voice without flashbacks to his earlier action hero roles. 

Case in point - his iconic refrain in "Taken": "I will look for you, I will find you, and I will kill you."

All things considered, his voice alone is enough to make us want to empty our pockets - especially seeing as it's for a good cause.

Dad-of-two Neeson urged the public to support the Children's Hospice Jingle "bigger and better" this year.

"Your support, no matter how little or large, will make a real difference."

He also thanked residents of Northern Ireland for grouping together to raise £167,000 last year. 

All profits raised from the campaign will enable NI Children’s Hospice to continue to provide infants, children, and young people living with life-limiting and life-threatening illnesses specialist palliative care.
