They will take to the red carpet in Dublin next month for the Irish debut of the acclaimed blockbuster 'Lincoln'.
But the glam factor will ramp up even higher following the January 20 premiere at Dublin's Savoy Cinema when Day-Lewis hosts a 'Lincoln'-themed ball at Dublin's Burlington Hotel to raise funds for the new Wicklow Hospice in Magheramore near his home in Co Wicklow.
He was inspired to raise funds for the hospice after seeing how well his mother was treated during her final days at a similar facility in England.
The star, who was recently named "the world's greatest living actor" by 'Time' magazine, has earned rave reviews in America for his portrayal of Abraham Lincoln.
The 'Gangs of New York' and 'There Will Be Blood' star said he can't speak highly enough of the Petersfield community hospital in the UK where his mother Jill Balcon spent her final days when she was diagnosed with an inoperable brain tumour in 2009.
"She was given great dignity that saw her through to the end of her life. So I was very grateful when Wicklow Hospice made contact with me as I wanted to get involved in any way that I could to establish something of that kind in my county of Wicklow."
Other cast members and other "surprise" celebrities have yet to confirm their attendance on the night.
Memorabilia from the film, including Day-Lewis's Lincoln costume, a signed original script, as well as a 15-litre bottle of Moet and Chandon champagne signed by the cast, will be auctioned.
