Doc Brown vs Doctor Who is the twenty-fourth installment of Epic Rap Battles of History and the ninth episode of Season 2. It features Back to the Future scientist, Doc Brown, rapping against the eponymous protagonist of his TV series, Doctor Who. The Doctor starts as the Tenth Doctor, then regenerates halfway through the battle into the Fourth Doctor after being fatally shot by a Dalek. It was released on October 29th, 2012.
This is the second battle to have two actors playing the same person.
At 1:14-1:20, the screen in the TARDIS is playing Minecraft.
This is an episode of "Shadow of Israphel", a famous series from YouTubers The Yogscast as confirmed by member Martyn Littlewood on Twitter.
The voices saying "Doctor", which can be heard during the Doctor's regeneration, mirror the portrayal of the Fifth Doctor's regeneration in "The Caves of Androzani". In the serial, the heads of the Doctor's companions appear around him as he lies on the ground in pain, and encourage him to stay strong during the process of his regeneration.
The second voice heard during the Doctor's regeneration sounds similar to the Doctor's robotic dog companion K-9.
Marty McFly's guitar solo is a reference to his performance of Johnny B. Goode at the Enchantment Under the Sea dance in the first two Back to the Future movies.
At 0:54, the hand that holds the TARDIS can be seen in the upper right.
However, it was possibly not an error, as it was seen while Doc Brown was mocking Doctor Who's special effects.
At 1:13, when the Fourth Doctor is laying on the ground, he does not have a hat on. When he stands up in the next shot, however, he does.
At 1:35, Doc Brown's hand gets cut off.
