Is Samuel L. Jackson the wounded bank robber who says Hey I gots to know in Dirty Harry?

That's a good guess, but no, Samuel L. Jackson is not the wounded bank robber in Dirty Harry.

The bank robber in question is played by John Vernon, a Canadian actor who was known for his villainous roles.

Samuel L. Jackson was not even in the movie *Dirty Harry*, which was released in 1971. Jackson's breakout role was in the 1991 film *Jungle Fever*.
