Doctor Who kicked off its storied television run on November 23, 1963 with 'An Unearthly Child', which saw the First Doctor spirit away two school teachers in his TARDIS for the very first time.
Current showrunner Steven Moffat has promised that Doctor Who will "take over television" during its anniversary, but has thus far revealed only that the episodes will "be full of tremendous surprises".
Coleman - who plays The Doctor's new companion Clara - has since offered her own hints about the 50th anniversary to The Sun's TV Magazine.
"[I'm] so very excited. Fifty years of Doctor Who and still going strong," she declared.
The actress went on to say: "It was amazing to see the response over in the US. The fans are mega-fans and its really rocketed in popularity over the past few years. I've been walking past the news stands in New York with Matt [Smith's] face gracing the covers of magazines.
"Steven [Moffat] texted me saying this will be something we will talk about in our dotage and he is right, we will. So watch this space!"
Coleman appeared in Doctor Who's festive special 'The Snowmen' as the Time Lord's latest companion Clara, a character who the actress described as a perfect "match" for Smith's Doctor.
"They are totally bemused by each other but are drawn together like magnets - they can't help liking each other but are constantly trying to work the other out."
Smith recently revealed that he will be staying in Doctor Who for at least another year.
"We've got Doctor Who's 50th anniversary coming up in November 2013, and one assumes there'll be another Christmas special after that, and I'd hope to be part of it," he hinted last month.
Doctor Who is to return later this year to BBC One in the UK and BBC America in the US.
