'Doctor Who' Series 7 filming updates ("Cubed") | Spoilers

Today, Doctor Who TV revealed some new spoilers regarding the fourth episode in the seventh series of Doctor Who.

The mysterious black cubes will apparently be carriers of a disease that release themselves upon a timer reaching the end of its countdown. The cubes will infect the Doctor and one of his hearts, for they seem to be immensely strong.

We also reported that part of the episode would be in the hospital seen in "The Eleventh Hour". Apparently this sequence will contain a young girl who has knowledge on the cubes, which sounds a lot similar to "Silence in the Library/Forest of the Dead."

Reportedly, there will be a brief sequence featuring King Henry VIII's residence, and DWT speculates that it is a pre-credit sequence, for most of the episode takes place in Rory and Amy's modern Earth.

As previously reported, UNIT is returning. While Martha may not be in this episode, a new UNIT character will be introduced. Her name is Kate Stewart.

Doctor Who returns in August.

'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. 

'Doctor Who' series 7 to debut in August (?)

According to The Guardian, The MediaGuardian Edinburgh International Television Festival will be debuting the opener of the seventh series of Doctor Who, the long-awaited return with the final season of Karen Gillan and Arthur Darvill, and the opening season for the Doctor's next companion, who will be played by Jenna Louise Coleman.

At last year's festival, Let's Kill Hitler was premiered and debuted on BBC the next day, so perhaps that will be the same case this year, meaning the episode could perhaps air on August 25!

What are you hoping to see from the Doctor's return?
