Matt Smith's final episode as Doctor Who saw both him and former assistant Karen Gillan wear hairpieces, the show's writer Steven Moffat revealed.
The Scottish actress made a brief appearance as Amy Pond at the end of the episode as viewers saw Smith bow out as the time lord and hand over the controls of the Tardis to Peter Capaldi.
Smith had to wear a wig after having his head shaved for his role in Ryan Gosling's film How to Catch a Monster, while Gillan had her hair cut off for the Marvel sci-fi film Guardians of the Galaxy.
Moffat said: "They're very good wigs but they're both wigs. Though in Karen's case that's her own hair. That wig is made of her own hair, it's just detachable now. When they cut her hair they made her a wig of her own hair. Didn't she look lovely?"
The show's writer also praised Smith's "heartfelt, brilliant and ancient" performance as an ageing Doctor was perfect, saying: "It's an end of an era, he should talk that way. You need a combination of huge sadness and lucky it doesn't end here".

The newly found programmes - which introduce the character of Alistair Lethbridge-Stewart, better known to audiences as The Brigadier - will be available on iTunes from today and will later come out on DVD.
Phillip Morris, the director of Television International Enterprises Archive, unearthed the programmes by looking up the records of overseas shipments of tapes made by the BBC.
The stories, The Enemy Of The World (1967) and The Web Of Fear (1968) and both starring Patrick Troughton as the second Doctor, have now been remastered by BBC Worldwide, the corporation's commercial arm.
Nine long-lost episodes of Doctor Who which have not been seen since the 1960s have been recovered after they were tracked down to a store room in Nigeria, gathering dust.
The discovery will cause much excitement for devotees of the long-running series, for which there are dozens of missing episodes dating back to its early years
The previously lost nine shows were among 11 traced to a television relay station and the find brings back to life an entire six-episode story, while another is almost complete.
An article penned by Peter Capaldi in 1976 and published in a Dr Who fanzine has appeared online. It comes after Capaldi was named as the star to replace Matt Smith as the Time Lord.
The article describes the opening sequence of Doctor Who and praises the 'artistic integrity and sensitivity' of Bernard Lodge, the man behind five opening titles sequences.
Clearly in awe of Lodge's work, and an avid fan, Capaldi writes: "The wonder of the opening is that it manages to capture in only a very few moments of screen time the atmosphere of Dr. Who."
He adds: "When that blue police box zooms in from a morass of complex light forms, there is no question of its right to be there. So already, within seconds of starting, the title designer has drawn us into the world of Dr. Who."
Glasgow-born actor and Oscar winner Peter Capaldi has been unveiled as the 12th incarnation of Doctor Who.Read the full story ›
