Its done in postprocessing as effect on your example, but originally this effect is from anamorphic lens which is associated with big budget films and its overused now for no reason. http://www.fsgso.pitt.edu/wp-content/uploads/2012/01/0732.jpg
Could be anything, as stated above the effect is from anamorphic lenses but can be done in post as well. The fixture doesn't really matter, although a cyc light would be rather wasteful in this instance since the majority of the output would be directed up and not out horizontally.
