Slumdog Millionaire: Canted angles (aka: Oblique angles)

According to Wikipedia, "The Dutch  angle, also known as the Dutch tilt, canted angle, oblique angle or German angle, is a type of camera shot where the camera is set at an angle on its roll axis so that the shot is composed with vertical lines at an angle to the side of the frame, or so that the horizon line of the shot is not parallel with the bottom of the camera frame" ( "Dutch Angle" Wikipedia ) 

As these shots from Slumdog Millionaire show us, this produces an effect of distortion and disorientation.
