UPDATE and solution (10 April 2012):
Number 23 was not yet five hours old and ↵ryoku already got it completely right: Max (William Conrad, on the left) and Al (Charles McGraw), ‘↑The Killers‘ (Siodmak 1946) they are! Here they are a minute later, having entered Henry’s Diner, at the counter—now Al is on the left:
 

Siodmak’s ‘The Killers’ is an absolute noir classic featuring non-linear storytelling. The first 20 minutes are a faithful adaptation of Ernest Hemingway’s short story of the same name (1927). The movie was Burt Lancaster’s screen debut and Ava Gardner’s first notable role, which made her career take off.
