One of my favorites, although probably not politically-correct anymore, is the British film, "The Dam Busters." It follows the story of an engineering team that attempts to design a bomb that bounces across a reservoir to destroy a series of dams in Nazi Germany. It's based on real events.
The Dam Busters (1955)
C.B. DeMille's 1956 "The Ten Commandments" in the scenes where the obelisk is being placed in Pharoah's new treasure city. Not crucial to the plot, but interesting and believable as to how ancient civil engineers might have done construction.
Later in this movie Moses is shown using a hand-powered bow drill to make a horn trumpet for his young son. A nice detail of domestic tool usage.
I also remember "No Highway in the Sky" although I haven't seen it in about 40 years. I think it may be related to the infamous structural engineering flaw in the de Haviland "Comet," the first production commercial airliner. It suffered from metal fatigue problems associated with stress points around the windows. It's a case study in most materials engineering courses.
October Sky (Rocket Boys) is my top eng movie. It captures that moment when you discovered your passion for science and engineering. Gotta love breaking out a physics equation to prove your innocence. Prodigious!
Once again, I refer to Robinson Crusoe on Mars. The main character, having crash landed and his comrade killed in the crash, must use all his science/engineering knowledge and skills to shore up his dwindling supply of food and water to survive long enough for the rescue ship to arrive. It's a bit corny in spots but not "Gilligan's Island" silly.
We were talking about this very thing last week on our radio show (http://theamphour.com). There's apparently a movie coming out about a young EE that invented a device that can translate movements into text. It will be directed by the guy that did "The Blind Side". The entire team making the movie looks pretty impressive, so it could be some great press for EEs.
My kids are big fans of the Disney Channel's "Phineas
and Ferb." The two brothers make all sorts of creative
(if entirely unrealistic) engineering-related gadgets
and buildings, and somehow manage to get it all cleaned
up before their mother comes home. Fun. And the spy-
vs-evil-genius subplot adds to the engineering feel.
