No one's going to be nervous watching Gervais as the sad-sack co-star of "Special Correspondents," a new Netflix film comedy written and directed by the star of the original BBC "The Office" and available for streaming on Friday. The story is pure "Wag the Dog," or, in this case, probably "Wag El Perro," as news-radio hotshot Frank Bonneville (Eric Bana) and his shlumpy sound engineer, Ian Finch (Gervais), are dispatched by their boss Geoffrey Mallard (Kevin Pollak) to Ecuador to cover a rebel uprising. The high comedic point of the film comes when Ian's vainglorious shrew of a wife, Eleanor (Farmiga), sees a chance to capitalize on her husband's apparent disappearance in Ecuador and launches a charity by performing a song she wrote herself called "Can You Spare a Dollar for a Hero?"
