Doctor Who is back tonight (April 15) and sees the introduction of Pearl Mackie as companion Bill Potts.

And, of course, every new companion that comes along needs a scene where they first enter the TARDIS, ushering in their first step into the exciting and weird world of The Doctor.

Ahead of the episode's airing, the BBC has uploaded a preview clip of that very scene.

Although she doesn't say "it's bigger on the inside", you can just tell that's what she's thinking. Good Face Acting, that.

If you want to know how Pearl Mackie got the job, she spoke to Digital Spy and revealed all about how she had to use a codename just in case her phone was bugged.

Meanwhile, showrunner Steven Moffat also told us all about how he creates a new companion character from scratch.

"You're not thinking, 'what gap has not been filled?' – and you mustn't. You can't say, 'Let's do the opposite of last time!' – that doesn't work.

"People aren't opposites of each other, and obviously the kind of people who travel with the Doctor are going to have certain things in common. On the other hand, as you will see, Bill is very different from [her predecessor] Clara."

Doctor Who series ten begins tonight on BBC One at 7.20pm. Get up to speed with everything you need to know right here.
