Adam Levine and Keira Knightley film scenes for Can A Song Save Your Life in Chelsea.

The Voice judge and Maroon 5 front-man Adam Levine joins British waif Keira Knightley on the new film project “Can A Song Save Your Life,” which is presently filming in NYC.

There are celebrities we like and then there are celebs who are likeable on screen but are hard to swallow when the cameras are not rolling and capturing their ill tempered and sour demeanor.  This post happens to contain one of each.  Completely incidental really.

These two are equally talented, if on their different fronts, but as it happens one comes across as a casual sexy motherfucker, while the other would do well to rid herself of her stand-offish cold bitch expression who can generate a fake ass smile at the drop of a hat.

Not judging, simply making an observation.

We dashed onto the set of the upcoming musically toned project, on our way back from Brooklyn, and found the duo filming on the streets of Chelsea.  Eureka.  But the moment went quickly south as Ms. Knightley has herself a goon who can play blockage better than an NFL pro-baller performing for an audience of recruiters.  All the while she is observable donning a less than pleased expression at the attention.

But as a true professional, the PA’s yell action and she washes it away and throws a smile on her face.

Word to Ms. Knightley:  a)  take it like the man you are co-starring with and deal with it.  Your goon will not dissuade any pap-er from trying to get the photo; and b) you look much prettier when you smile…  Think of happy thoughts when you are down in the trenches – i.e.: Like when you were a start-up and were gagging for it!
