Doctor Who's latest trailer for series 8 is only around sixteen seconds long. That is, until two fans got their hands on it.
Yes, the brand new "Am I a good man?" trailer, which launched on Friday night featuring new Doctor Peter Capaldi and companion Jenna Coleman as Clara, has already had a fan makeover.
The BBC's teaser trailer didn't exactly disappoint. It revealed that the series would begin on August 23 with a first episode entitled Deep Breath. And although the date clashes with some birthdays and holidays, most fans seem pretty chuffed with it (check out reactions here).
But of course, fan trailers can be outstanding. We picked out our favourites when the previous trailer got tweaked by digital-savvy fans.
Now, the Doctor asking Clara if he's a good man gets embedded into extended fan footage thanks to the efforts of YouTube users Peter Phillips and Ashley Woolston.
