there was a movie made back in the 90's about a company that allowed you to go back in time to witness disasters, haven't seen it in forever and have since forgotten the name, would love to see it again...
I tried "90s time travel movies" in Google and found "Timescape" aka "Grand Tour: Disaster in Time" with Jeff Daniels from 1992 - hope that rings a bell :)
I feel like I've walked into an upmarket store where I don't belong. Thanks everyone, my day has been well and truly made. :) (meme correct at time of writing)
