We often see ship hull breaches in space movies, but do they accurately depict the vacuum's pull?

Subquestion:
IRL how strong is the vacuum's pull?

The vacuum "pull" is nothing but the internal pressure pushing against a lack of external pressure. So the force is given by a pressure differential of about one atmosphere acting on the area of the breach. For a small hole this is not a lot at all: Atmospheric pressure is 1 bar = 10^5 Pa = 100000 N/m^2 . If you have a breach with a cross section of 1 m^2 , the force would be 100000 N, i.e. roughly the equivalent of of 10 tonnes of weight distributed over that area. A hole with 100 cm^2 area (a fist sized hole in the hull) would only have 1000 N force, roughly 100 kg worth. Enough to lose air, but if you want to plug such a hole by putting e.g. a body part or a book on it it will hold.  

If you have access to a vacuum pump (e.g. in a science lab) put your finger over the tube and you will feel a slight pull - this is exactly what would happen with the space scenario. 

Movies rarely let science get in the way of a good story.
