Script Spoiler.

Thanks for Ryan from Through the Anomalies for this post and to the owner of the video, which can be found here.

In another interview with Adrian Hodges, a part of a script for Series 4 can be seen on screen. It is hard to make out the words, but it seems that a Pliosaur, possibly a Liopleurodon, which has appeared in the Impossible Pictures production Walking With Dinosaurs, will attack a Submarine that Danny Quinn, last seen stranded in the Pliocene, is on board. And there is not just one Pliosaur, but a whole group of them!

Pliosaurs, for those who don't know, were marine reptiles from the Jurassic and Cretaceous era. Pliosaurs were also some of the largest carnivores ever. Some could up to huge sizes, and some liked to prey on Dinosaurs. Looking closely at the script it seems that the Captain of the Submarine may be killed in a scene, as somebody called K.P. says 'We've lost all power. And the Captain.' Reading more it seems one Pliosaur attacks the submarine and brings down its propellor and the Captain. The crew are all scared, and then they find themselves surrounded by a pod of Pliosaurs. I doubt this Captain is Becker, but lets keep our fingers crossed that he's alright.

In other news, it seems Danny will not be appearing in all of Series 4, according to Adrian Hodges, he will not necessarily come back at the beginning of the season. In fact Hodges said in an interview that alot of the first couple of episodes will focus on how some of the characters get back from the past. From the filming pictures, we can assume this is Abby and Connor.
Adrian also hints at the idea of Human intervention from the future and a variation of monsters from the future.

Well this is all very interesting, and pretty squeeworthy, as Pliosaurs are a great monster from the past, rivalling T-Rex in my opinion. Thanks to Ryan again!
