#4. Brendan Gleeson
The strongest “character” actor on this list, Gleeson tends to pop up just about everywhere, from big-budget franchises to little-known gems while displaying a wide range of ability throughout a multitude of genres. Having worked with Scorsese, Spielberg, Boyle, and a whole host of other celebrated directors, Gleeson has earned his place in cinema as one of the most reliable names working today. Keep an eye for the films where he actually plays the lead, they’re usually first-rate.
