BBC has really outdone themselves. This is one of the coolest TV show trailers we've ever seen.
Ahead of the return of "Sherlock" on the network next month, BBC has released an interactive teaser for the show. While watching, a bunch of prompts pop up with the option for fans to view extra content about the series.
At the end of last season *spoiler* it appeared Sherlock (Benedict Cumberbatch) saw his demise; however, it was revealed at the episode's end, that he was indeed alive! How he survived a seemingly inescapable death has yet to be revealed. *spoiler*
Turns out Sherlock has been gone for two years.
If you were hoping for John Watson's (Martin Freeman) mustache to be sticking around for a long time, don't get too excited. It looks like Sherlock hates it.
"Sherlock" returns January 1, 2014 on BBC One and will premiere in the US January 19 on PBS.
