Finding fame and fortune as a film actor has long been one of the most coveted career paths there is for creative dreamer types. How wonderful we imagine it to be, working with all manner of great writers and directors to create great works of cinema - to say nothing of all that money and adulation that goes with it.
When all is said and done, though, acting's just another job like any other. Some days you show up feeling all inspired and raring to give it your all; other days you're just not feeling it. And, a hell of a lot of the time, the only thing that keeps you going is looking forward to payday.
Even the most well-known, admired actors in the business struggle to bring their A-game every single time. Maybe they've got problems with the script or the director; maybe they've got off-camera issues affecting their work. Or, again, maybe the only reason they signed on in the first place was for the money.
Whatever the reasons may be, even Hollywood's finest fumble the ball from time to time.
