Karen Gillan has claimed her Doctor Who companion character Amy Pond is a "lot cooler" than she is.
Speaking after the first part of the season finale was screened on Saturday, Gillan said Amy was one of the most interesting assistants for the Time Lord due to her willingness to stick up for herself.
"I do think she's different from previous companions of the Doctor because she's very equal to him," Gillan told the People.
"She doesn't take his word as gospel and she's always happy to challenge him. If he tells her to do something then she won't necessarily do it.
The Scottish actress added the relationship between the characters could be explosive, saying: "The Doctor is definitely an alpha male and Amy is an alpha female so when they meet, they combust.
"They have quite a turbulent relationship but it's also really passionate and they care about each other. Amy can really hold her own against him. It's a great relationship."
The final episode of the current series of Doctor Who is screened on Saturday at 18:05 BST, with the broadcast date of the episode - June 26th - crucial to its storyline.
