It’s 1921 and three children (Stephen, Victoria and Conrad) are spending an idyllic summer at a Cambridgeshire manor house, enjoying sophisticated garden parties and running free in the surrounding countryside.

When a childish prank goes wrong, Victoria disappears into a well. However, a chance meeting with a mysterious professor sets Stephen and Conrad off exploring the possibilities of time, or dimensional, travel and, perhaps, a way of saving Victoria.

Things that British film and television do really well are period costume dramas, children’s stories and sci-fi. Dimensions does all of these and even throws in a love story as its central motif.

If Merchant-Ivory had ever made a time travel movie, with steampunk elements, (and shot it on a DSLR) then this would be it.

This is classy, intelligent filmmaking that needs to be seen and supported.
