New 'Doctor Who' trailer, dissected shot by shot

Get ready for Tardis-spinning adventure with the Doctor and his pals in "Doctor Who" season 10, starting April 15. Let's obsess over the new trailer, shall we? Warning: possible spoilers ahead!

This unusual pyramid is in a forest on Earth, or maybe another planet altogether, which should thrill fans of the "Ancient Aliens" TV series who like to point out pyramids were built by extraterrestrial life forms.

People running away in a field from a cloaked creature makes for an interesting glimpse into what new enemies lie in wait for the Doctor and his friends.

This could be a modern-day space station, perhaps ISS or maybe a future SpaceX project. Either way, the Doctor would be impressed.

The familiar blue and orange lights inside the Tardis welcome new travel companion Bill Potts (Pearl Mackie).

The Doctor (Peter Capaldi) inside the Tardis, just as we expect him to be. Too bad this is Capaldi's last season as the Time Lord.

This new landscape looks like a breath of fresh air compared with the usual stopping off-points for the Doctor. But often things aren't as safe as they initially appear.

When the Doctor and Bill meet this emoji robot, it looks like they have made a new droid friend.

When the Doctor and Nardole (Matt Lucas) suit up like astronauts, this could mean they're trying to blend in with a space station crew.

No "Doctor Who" season is complete without a trip back to London's Victorian past.

If you travel with the Doctor, be prepared to upset the natives once in a while.

New companion Bill Potts (Pearl Mackie) could bring a fresh viewpoint to the series. In the trailer she's excited to be anywhere with the Doctor.

Nothing like a gigantic eyeball to make fans wonder what the rest of the creature looks like. Also, this looks like it could be underwater.

It wouldn't be a proper "Doctor Who" season without the Daleks. Here's the machine bent on the destruction fans have come to fear.

But what of this human girl who seems to be shouting the same Dalek motto of "Exterminate"? Is she a Dalek in the ultimate disguise?

These humans holding guns might be shielding their eyes from an explosion or a bright light from a spaceship. Either way, it will be fun to find out what happens next.

Did the Tardis land on Earth or is this a newly terraformed planet that humans inhabit?

The bigger the door, the bigger the threat. But for the Doctor, this door might open up to something in his past -- if we're to guess from the age of that painting off to the side.

This explosion can't be a good thing if we go by the Doctor and Bill's shocked facial expressions.

Character actor David Suchet, best known for his role as Agatha Christie's Hercule Poirot), stars in the "Doctor Who" episode titled "The Landlord." Here he's holding a tuning fork, or is it something more magical?

This emoji robot seemed friendly at the beginning of the trailer, but when it starts communicating with skulls, the outlook doesn't look so happy.

Missy (Michelle Gomez) is back, but what does that mean for the Doctor and his friends?

This new alien race looks like it could be made from wood, or maybe they're some kind of ancient forest people?

This isn't the first time the Doctor and his friends have had run-ins with soldiers. Here's hoping the military is on the right side.

This new race of aliens could be a threat or new allies. As "Doctor Who" fans, we know not to judge just by first impressions.

The Doctor often loses his temper, and this Victorian lad is unlucky enough to find out that Time Lords know how to fight.

All of the Doctor's companions cry at some point. But is this the moment the Doctor dies and regenerates into the actor replacing Capaldi?

The original Cybermen first appeared in 1966. Now they have returned in their retro form for episodes 11 and 12, and they still look just as menacing.

Lizard-like people are nothing new in "Doctor Who," especially the Silurians. This is a quick shot a race of an Ice Warrior -- reptilian humanoids from the planet Mars, identified by the Eleventh Doctor.

When a giant water creature's after you, it's best to run as fast as you can toward the Tardis and hope for the best.

This will be the last time fans will see a smiling version of Capaldi's beloved Time Lord as season 10 is his final season as the Doctor.

Nardole (Matt Lucas) is thrown a sonic screwdriver that looks like it could have previously belonged to the Fourth Doctor.

The Doctor tries to get the attention of one of his friends. But is he in a Shakespearean theater such as the famous Globe Theatre?

Nardole (Matt Lucas) and Bill Potts (Pearl Mackie) run with the Doctor (Peter Capaldi) in the next season, which looks like they could be facing interesting foes.
