The long-running show will air live as part of its 50th anniversary celebrations in December, and reports have suggested that the special edition will focus on the aftermath of the upcoming tram crash stunt.
Speaking to Inside Soap about what is in store, Collinson explained: "In the first instance, I thought we wouldn't go live, but quickly realised we should. I think we can deliver the most spectacular piece of live television people have ever seen.
"Coronation Street has such a heritage - the first episodes were filmed that way, and we did it ten years ago. My ambition is for the episode to be like a disaster movie with stunts.
"It'll be action-packed. I want people to sit at home and think, 'There's no way they did that live, not in a million years!'"
Alison King - who plays Carla Connor on the show - recently told DS that she is feeling nervous over her involvement in the episode. Get the Inside Soap magazine on your iPhone or iPad
