Downton Abbey star Jim Carter cut the ribbon to open a new cinema room at The Granby care home in Harrogate on February 17.
The facility for residents, families and visitors, is part of the Grade II listed building's £2m refurbishment this year.
Jim Carter's mother Molly, 98, resides at the home, and was among the many residents gathered there to witness the big moment.
Mr Carter said: "I think it all looks very smart. I love that my mother and the other residents now have somewhere to watch their favourite films and relax in beautiful surroundings.
"The colours in the new dining room are wonderful and the home has a wonderful homely feel to it. The staff here have always been really nice and helpful, but this now makes everything feel even more comfortable and we can’t wait to see the final results of the full refurbishment very soon."
Interior designer Rachel Warrington said: "We have been wanting to refurbish The Granby for a while and we are so excited to be doing it.
"We are trying to pay respect to the Georgian heritage while also giving it some modern features at the same time."
"Going to the cinema room is a lovely way to spend an afternoon, it is a great way to bring everyone together in such a comfortable setting."
Manager Karen Auker said “We would like to thank Mr Carter for coming along and giving up his time to help us open our stunning new cinema room. We are looking forward to him popping in to watch some films with his mother."
The home's latest refurbishments are scheduled to be finished by September this year. These include redecorating all the bedrooms, creating a new lounge and conservatory, and redecorating all bathrooms and corridors.
