“One Ranger” (*1/2 out of four) was a leaden action melodrama about a Texas ranger (Thomas Jane) who is recruited by the C.I.A. (led by John Malkovich) to stop an international terrorist (Nick Moran) from wreaking havoc on London. Drably told story makes you yearn for the golden touch of Sam Peckinpah or even Walter Hill. Heavy on tongue-in-cheek attitude but everything else about it is heavy as well, including Jane’s overbaked accent. Malkovich is wasted in yet another easy paycheck role.
