The 'Doctor Who' 50th anniversary special will be broadcast in 3D.
The BBC has announced the episode - starring Matt Smith as the titular Time Lord - will be filmed using the latest TV technology and showrunner Steven Moffat is very excited about the possibilities 3D brings.
Making a reference to the Doctor's TARDIS spacecraft - which is famously "bigger on the inside" - Steven said: "It's about time. Technology has finally caught up with 'Doctor Who' and your television is now bigger on the inside. A whole new dimension of adventure for the Doctor to explore."
Details of the episode, 'Doctor Who: The Light At The End', remain scarce, but speculation is rife the adventure - which will be broadcast in November - will bring back former Doctors such as David Tennant and Christopher Eccleston.
Matt, 30, previously revealed a 3D adventure was at the top of his wishlist for the 50th anniversary.
Speaking to BANG Showbiz in 2011 ahead of the launch of the second half of Series 6, he said: "I love making 'Doctor Who' and I get to be part of that 50th year, which they'll do something mental for. You know it will be brilliant.
"I'm interested in all the 3D stuff. If it could be filmed for 3D TV that would be fun, especially with 'Doctor Who', but it's very expensive. I don't know how they'd do it."
Ahead of the anniversary, 'Doctor Who' returns to BBC One on Saturday, March 30 for a run of eight episodes.
