POOR Marty Scorsese.

He’s widely expected to lose – again – at the Oscars Sunday night, and, to add insult to injury, a producer has dug up an undistinguished 1997 vanity project in which Scorsese was cajoled into playing himself and has booked it into a rent-a-screen at the Village East.

“With Friends Like These . . .,” an inside-baseball show-business comedy that’s been available on video since 2001, has a solid cast bogged down in the broad script and lethargic direction of one Philip Messina.

Johnny (Robert Costanza, a former regular on “NYPD Blue”), a sporadically employed, bald, fat character actor specializing in two-bit goombah roles, is summoned by a bulimic casting director (Beverly D’Angelo) to try out for the role of Al Capone in a movie being directed by Scorsese.

But before you know it, the lug is competing with his back-stabbing actor buddies played by Adam Arkin (“Chicago Hope”), Jon Tenney (“Brooklyn South”) – and John Sayles veteran David Straithairn, a most unlikely Italian-American who somehow manages to make something interesting of his role as an actor who may have real-life mob connections.

But despite a cast that includes such luminaries as Amy Madigan and Laura San Giacomo, as well as cameos by Bill Murray (as a freeloading producer) and Scorsese as himself (who was much funnier on “Curb Your Enthusiasm”), “With Friends Like These . . .” is only sporadically amusing.
