Jack Elam needed almost no dialogue to create one of the most unforgettable openings in Western history.

In Sergio Leone’s 1968 classic Once Upon a Time in the West, Elam plays one of three gunmen waiting silently at a lonely railroad station. His most famous opponent isn’t another cowboy — it’s a fly crawling across his face.

To capture the scene, Elam later recalled that apricot jam was placed on his beard to attract real flies, with filming taking roughly a day and a half before Leone got what he wanted.

But Elam’s famous wandering eye had a much deeper story.

A childhood accident left him blind in his left eye. Years later, while working as an accountant, doctors warned that the strain of paperwork could endanger his remaining good eye. He eventually left accounting and turned toward acting.

The feature that once complicated his life became part of the face audiences would never forget.

Elam went on to appear in scores of Westerns and television shows, including Gunsmoke and Bonanza, before his death in 2003 at 82.

And more than 50 years later, that strange, nearly silent encounter between Jack Elam and one stubborn fly remains one of the great moments of the Western genre.
