In 1987, when the original 21 Jump Street debuted, Johnny Depp secured his sure-shot trajecotry to fame as Officer Tom Hanson, a fresh-faced undercover cop who infiltrates the youth crime scene.

Twenty-five years later, newly-minted leading men Channing Tatum and Jonah Hill are looking to bring new life, and some laughter, to the once heavy-hitting concept of adults going undercover as kids. The Phil Lord and Christopher Miller directed film will make its way into theaters this Friday, and Depp himself will even make a brief—but totally amazing—cameo.

While we're not worried about Depp's screen time, we're not sure if we're alltogether convinced that Tatum and Hill can pull the cops-posing-as-teenagers shtick off. The good news is, if they fail, they will be in good company. Hollywood has a habit of routinely casting characters whose incognito status is dubious at best. Sure, sometimes the least plausible characters are intentionally cast for laughs, but oftentimes covert cops are actually meant to be convincing, and just aren't up to snuff. Here, we'll look back on all of those clandestine cops that have raised our skepticism and failed to suspend our disbelief: The 10 Least Believable Undercover Cops in Movies.
