'Doctor Who' Series 7 casting updates, filming information | Spoilers

Doctor Who TV has provided a list of spoiler-ish information regarding the fourth episode of the seventh series of Doctor Who, which is the last episode that Karen Gillan (Amy Pond) and Arthur Darvill (Rory Williams) are filming, although their respective characters' last episode has already been filmed (episode five).

• Steven Berkoff (whom you may have seen as Dirch Frode in The Girl with the Dragon Tattoo) will be playing a character called Mr. Shanks
• Ruthie Henshall is also reportedly playing an antagonist in the episode, currently titled "Cubed."
• The Doctor's arrival will be during Amy and Rory's wedding anniversary/BBQ, which will also feature Mark Williams, who is playing Rory's father, Brian.
• The Neath Abbey and Cadoc's Hospital are returning as filming locations. They can be seen in "The Rebel Flesh" and "The Eleventh Hour," respectively.
• The Doctor is tampering around with those mysterious black cubes again. Perhaps they are somehow linked to either Berkoff's or Henshall's character.
• Today is also reportedly Karen and Arthur's last day of Doctor Who filming, which is obviously very sentimental.

We wish Karen and Arthur the best of luck in their future endeavors, and we hope that they enjoy every single lasting bit of Doctor Who they have, and that they know they will be remembered. They truly were great! 

The seventh series of Doctor Who debuts this August.
