Steve Blum
Steve Blum is an actor, born 1960.
Steve Blum has one of the most recognisable voices in American animation and almost none of the public recognition that should go with it, because the parts that made him famous arrive through anime dubs, cartoons and video games rather than film premieres. The instrument is the asset: a low, sanded-down growl that reads as tired rather than tough, which is why he keeps getting cast as men who have already seen how these things go.
Spike Spiegel in Cowboy Bebop is the performance most people mean, and that series is not among the credits listed here. What is here covers the rest of the range. Amon, the masked revolutionary in The Legend of Korra, is the best-written role he has been handed. Starscream in Transformers: Prime is played as a wheedling courtier. Zeb Orrelios in Star Wars Rebels is a large angry alien with a soft middle, and Wolverine, whom he has voiced across a decade of Marvel cartoons, is the growl used exactly as intended.
Games are the other half of the working week: Tank Dempsey in the Call of Duty zombie modes, Sub-Zero in Mortal Kombat, Ares across three God of War titles. Then there is the invisible tier that pads out this filmography, the additional-voices credits on Incredibles 2, Lilo & Stitch, Hotel Transylvania 2 and dozens more. That is the ambient crowd noise of American animation, and Blum is in more of it than any credit list can properly show.

Where to start with Steve Blum
The famous one, Spike Spiegel in Cowboy Bebop, is not among the credits listed here, so begin with The Legend of Korra. Amon is Blum with the volume turned down: a masked revolutionary who never raises his voice and is far more frightening for it.
Then take the two ends of the register. Transformers: Prime has him playing Starscream as all whine and no spine, which is genuinely funny, while Star Wars Rebels gives him a bruiser with a soft centre and Wolverine and the X-Men is the definitive version of his Logan.
If you want a sample without committing to a season, The Witcher: Nightmare of the Wolf and Mortal Kombat Legends: Scorpion's Revenge are animated features that use him properly, and Transformers One shows how much of the modern career is background texture inside very large films.
The animated superheroes
DC animation has used that voice for two decades, usually as the thing in the dark. The Legend of Korra gives him Amon, a masked revolutionary with a genuine argument, which is the best-written villain in any of it.
Wolverine, over and over
He has played Wolverine more than any other actor, across a decade of Marvel cartoons and features. Wolverine and the X-Men is the run to hear: a full season built around the character rather than a guest slot.
Star Wars, Transformers and the family films
The franchise work pays for everything else. Zeb in Star Wars Rebels is four seasons of a genuine lead, Starscream is the Transformers role, and the animated features let him do something other than menace.
