Maybe you’re tired of seeing the phrase “seems almost totally disconnected from rational decision-making” on your performance review. You get discouraged because the boss begins every assignment with “Try not to screw this up …” Well, there’s not much we can do to salvage your career from clear over here, but we’re willing to help with your self-esteem.

We suggest that you visit www.moviemistakes.com on your lunch hour and revel in the bone-headed goofs that litter multimillion-dollar Hollywood films. By comparison, you’ll seem much closer to adequate.

In “Pirates of the Caribbean: The Curse of the Black Pearl,” for example, as Capt. Jack Sparrow says, “On deck, you scabrous dogs,” look past his shoulder and you’ll see a crew member in a cowboy hat and sunglasses, ignoring Johnny Depp’s high-powered acting and gazing out to sea. If they can leave that in the final cut of a major motion picture, how can you be blamed for accidentally posting secret company memos on Facebook?

Moviemakers have an advantage, because they have crew members who are paid to keep a laser-like focus on continuity. Their role is to make sure that objects and actions are consistent, even though a scene may have been shot in several takes, and the takes may have been separated by a fair amount of time. As I understand it, a large part of moviemaking is sitting around waiting for the stars to emerge from their trailers, finally prepared for another grueling 10 minutes of playing make-believe.

Yet in “Star Wars: Episode V – The Empire Strikes Back,” Han Solo has no jacket as the bad guys march him toward his appointment to be frozen in carbonite, then two seconds later he’s wearing a jacket. Either the continuity person was snorting carbonite, or Executive Producer George Lucas had started taking the audience for granted. “I can’t believe they took Chewbacca seriously,” he may have thought. “Let’s see what else I can put over on these mopes.”

Then there’s your situation. You have to show up for work almost on time, come up with fresh things to complain about, get some coffee and figure out where to go for lunch. Plus your assigned duties.

Providing you with a continuity person is the least the company could do.

Either way, remind your supervisor that big mistakes don’t necessarily doom a project to failure.

The next time you watch “The Godfather,” pay attention to the scene where Sonny Corleone is shot to death, or maybe even a little past death, at a toll booth. Bullets shatter the windshield of his car. When his bodyguards arrive a few seconds later, the windshield is intact.

And yet, the audience was satisfied. Anything to get James Caan out of the picture.

I hate to ruin even a small part of the upcoming holiday season for you – well, “hate” might be too strong – but here’s a prediction: The next time you watch “It’s a Wonderful Life,” you’re going to notice that George Bailey tosses a wreath onto a desk as he comes into the building and loan office and is told that his hero brother is on the telephone.

As he picks up the phone, you’ll notice that the wreath is on his arm. Now, that is an unlikely bounce.

Decades have passed since that scene was shot, but it hasn’t been enough time for Hollywood to come up with an effective mistake-avoidance system – computerized grid analysis, perhaps, or paying attention. In the 2009 movie “He’s Just Not That Into You,” Jennifer Aniston at one point refers to Ben Affleck’s character as “Ben” instead of “Neil.”

They could have rehired the immortal actress to re-record that single word, but that probably would have been another million bucks.

Actually, instead of just taking solace in these foul-ups, coax your supervisor to take a look at them, too. “See, I’m not inept,” you’ll say. “I just operate according to West Coast standards.”
