Directed and written by Mark Gatiss, 'The Mezzotint' premieres on BritBox on December 24.

"The show starts off with these two best friends who come out of hibernation, which is akin to what's going on with our world...It's nice to see them navigate the ins and outs of their crazy, critter lifestyles."

"I hope [audiences] go away with a lot of quotations besides 'bah, humbug!' and with little pearls of Dickens' wisdom about mankind."

"I quite like oranges. I've been reviewing oranges to figure out where in Richmond they sell the best ones."

Patrick Harbinson recalls memorable days on set and explains how actresses Gemma Whelan and Tahirah Sharif really delivered.

"Because it's a Christmas [story], every year around Christmas it'll be revisited and played. It's a timeless story that is never going to be outdated."

"What's very special about this 'A Christmas Carol' is that it bursts through all of the rooms. Every scene you watch is actually in Charles Dickens' house!"

"It's an incredibly appealing play for everybody no matter what your beliefs are and your religion. It embraces all the good parts about humanity."

"I have enormous respect for the mustang. They are tough and majestic! You could make the case that they should be the animal representing this country."

"I hope the story of love of community and sacrifice is clear and evident to people. That's what we need more of now and we'll need more of 20 years from today."
