You're thinking of Maverick (in which Gibson stars as the title character and Glover appears in a Lethal Weapon-referenced cameo).

To the o.p., no, a finger won't cause enough of a blockage to prevent the bullet and exhaust gases behind it from exiting. A drop of water in the barrel of a rifle or musket, however, can be enough to jam the bullet against the barrel and cause it to bulge or split. Cannon shells may explode their charge for reasons previously indicated.
