Forced myself to gag, drank mud before 'The Lighthouse' scenes: Robert

Actor Robert Pattinson has revealed that to maximise creativity, he used to punch himself in the face, or drink mud, or force himself to gag before scenes for 'The Lighthouse'. He explained that he doesn't "really know how to act" and did it to make his acting seem "real". "[I]f you shake up your physical state...You...[walk] into...scene having...different...feeling," Robert added.
