The BBC is slowly breaking down the cone of silence that has surrounded the filming of the Doctor Who 50th Anniversary Special and fans can view a brand new clip from the upcoming episode.

Featuring the Eleventh Doctor (Matt Smith) and Clara (Jenna-Louise Coleman), the new smidgen of film appears to take place inside the London National Gallery. As a worker uncovers a gigantic painting, someone mutters something about Queen Elizabeth's credentials while Clara looks on in disbelief.

While it's difficult to puzzle out what is on the painting, the mention of Queen Elizabeth and the Gallery setting help to tie together a few strands from a recent plot synopsis.

New plot details that have emerged for "The Day of the Doctor" state that while something stirs from within the London Nation Gallery in the present day, a killer advances on his victim in Elizabethan England, and somewhere in space an old war draws to a close.

A BBC interview with Joanne Page, who will portray Queen Elizabeth I, also helps shed some light on the monarch's role in the three Doctors' adventure - particularly her role as the Tenth Doctor's love interest.

"Filming the romantic scenes were quite difficult because my first day was on top of a mountain in Neath. It was absolutely freezing, it was blowing a gale and David, the Tenth Doctor and I, are having a picnic," Page recalled, according to the BBC. "So I'm lying across him and he probably couldn't breathe, because I've just got this massive costume on, and he's feeding me grapes as I'm just desperately shivering...So everyone is probably jealous, thinking she gets to kiss the Tenth Doctor and it's all romantic, but it's not; my lips were numb and my hands were chapped."

"The Day of the Doctor" will be broadcast worldwide on Nov. 23.
