'Doctor Who' Season 7 trailer: Daleks and dinosaurs

"Doctor Who" will return to BBC America in the fall, and -- just a guess here -- the trailer released Wednesday (Aug. 1) will have fans pretty fired up.

It opens with the Doctor (Matt Smith), Amy (Karen Gillan) and Rory (Arthur Darvill) facing a huge assembly of Daleks, zips to dinosaurs running amok on a spaceship (Smith's delivery of the line "Dinosaurs ... on a spaceship!" is pretty great), zips over to what looks like the Old West and ends with the Doctor carrying Amy in his arms.

So, yeah: It's good. It also features some shots of Weeping Angels, who apparently figure into Amy and Rory's final episode, which airs midway through the season.

"Doctor Who" returns to BBC America in the fall; there's no specific date yet. What do you think of the trailer?
