A few SJA titles and synopsis

1: Revenge of the Slitheen
"One of the discussions we had at a very early stage was whether we wanted to start in a school. In the end we decided to go with a school for episodes one and two because it was a very familiar and natural environment for kids to recognise and empathise with."

2: Eye of the Gorgon
"It features a slightly bizarre group of women who go around dressed as nuns but it's much camper and more overblown - it's less rooted in everyday life. It's probably the most effects-heavy of all the episodes, because it's quite out there."

3: Warriors of the Kudlax
"That is more of a classic Sci-Fi story, in the sense that there's laser gunfire and running around and being pursued by dark suited guards and things. It's more in the mould of Star Wars."

4: Whatever Happened to Sarah-Jane?
"It does touch upon Sarah's childhood and one childhood friend in particular and a tragedy that has taken place in her past that comes up from the meddling of a particular evil alien character called The Trickster. He sort of exists to create chaos. We hope it has a flavour of Back to the Future, the idea that you can have alternative realities where you see how characters could have developed with different influences."

5: The Lost Boy
"That is a fitting and surprising climax to the series where various twists happen."
