Andrew-Lee Potts, Hannah Spearritt and Ciarán McMeniman are back with the fifth series of time-travelling dinosaur drama Primeval.

In the fourth episode of the new series, Philip and Connor secretly open an anomaly within the ARC, only to be invaded by a mass of scurrying future-beetles, who force the ARC into lockdown.

Episode 4 airs at 5.30pm on Saturday 7th July on ITV1. In the meantime, here are ten teasing lines of dialogue from the episode…

» “Never apologise for your work, Connor. You’ve earned your stripes.”

» “You’re not going to believe where this anomaly is…”

» “I suggest you turn around and leave this lab immediately – because under no circumstance is anyone going to lock this anomaly.”

» “This is bigger than just Connor’s lab!”

» “There are wars going on right now over energy and shortages that cause economies to collapse. We can end all of that.”

» “Scientists are always messing with nature! It’s what we do! It’s called progress.”

» “You think that was bad? It hasn’t even started yet…”

» “Those things will breed. We’re talking about a plague.”

» “What you’re doing here, it’s going to change the whole planet. If it comes to it… isn’t that worth the sacrifice?”

» “It’s too late. There’s no way we can stop him now.”
