With the return of Doctor Who and Sherlock coming in the next few weeks, YouTube user Josh Smith has found a way to bring both shows together with his fan-made trailer for Wholock. Sherlock star Benedict Cumberbatch is seen stepping out of his home on Baker Street to find Matt Smith's Time Lord outside in his TARDIS machine. In addition, we also have a video that breaks down the visual effects that make this trailer look so real.

Doctor Who returns with its annual Christmas Special, The Time of the Doctor on December 25, which marks Matt Smith's final turn as the Doctor before Peter Capaldi takes over next year. Sherlock Season 3 debuts on January 1 on BBC and BBC America.
