Charles Williams (September 27, 1898 – January 3, 1958) was an American actor and writer.

[1] The actor with the short stature and high-pitched voice[1] was often uncredited for his appearances, although he had larger roles in a number of B movies.

Williams was known as a "B-movie regular", who often portrayed quirky, somewhat nerdy, bespectacled clerks, photographers and especially reporters.

[2][1] He is perhaps best remembered today[citation needed] for appearing in It's a Wonderful Life as Eustace, George Bailey's cousin and co-worker at the Building and Loan.

Near the end of his life and career, Williams also played in a number of television series.
