Actor slits his own throat as knife switch turns fiction into reality | Stage | The Guardian:
An actor slit his throat on stage when the prop knife for his suicide scene turned out to be a real one.
Daniel Hoevels, 30, slumped over with blood pouring from his neck while the audience broke into applause at the "special effect". Police are investigating whether the knife was a mistake or a murder plot. They are questioning the rest of the cast, and backstage hands with access to props; they will also carry out DNA tests.
Things went wrong at Vienna's Burgtheater as Hoevels' character went to "kill himself" in the final scene of Friedrich Schiller's Mary Stuart, about Mary Queen of Scots, on Saturday night
It was only when he did not get up to take a bow that anyone realised something had gone wrong.
