Every actor has those days when they just can’t keep it together and, despite trying their damnedest to hide it, the laughter just comes pouring out. This rule does not exclude the cast of Harry Potter and the Deathly Hallows, in particular Ms. Emma Watson, who was caught on BTS film ruining bunches of scenes and laughing in the face of Rhys Ifans.

If this isn’t fun enough, the cast is ordered to put their own money into a jar when they’re the ones who screw up scenes. Not surprisingly, it’s usually Rupert Grint as Ron Weasley who can’t keep his act together during shoots, but apparently on this day Watson wasn’t as poised and studious as her on screen counterpart.
