"Honey, I shrunk the kids."   Maths in the Movies.  Project 14.

From the script...

Nick ,  I am now ¼ of an inch tall.
64 feet from the house its equivalent to 3·2 miles.
It's a long way even for a man of science

Nick again, A butterfly with a wing span of 42 feet!

How tall is Nick ?
Is he correct calculating the butterfly ?
Name the movie !
