....no mustache?
in fact, it's one of the only movies or TV shows where you'll ever see Tom sans the mustache.
He does have a mustache in this movie, as shown in this scene:

If you want to see him without one look at the earlier movie Coma (1978) as well as In and Out (1997)
In movie promotion there’s always been a vast chasm between what’s promised and what’s delivered. Sometimes it’s an honest problem with logistics; that is to say, the production hit an unavoidable snag and deadlines or low budgets get in the way. Ad campaigns commence months or years before a projected release date and the snags are unforseeable.
Or on the other hand, sometimes it’s willful misrepresentation (lies!). The movie industry has always attracted a large number of hucksters.
