Orthodoxy in Comic Books
It would seem that, aside from the movies, comics are a particularly wealthy (relatively speaking, of course) source of such 'Orthodox sightings'. Here are two more I have found during the past few months:
The first comes from a Daredevil comic:
Natalia Romanova (a.k.a. Natasha Romanoff, the Black Widow) exclaims 'Glory to God' after an attempted assassination is prevented. Now, this isn't "Orthodoxy" per se, but it is an expression heard often enough in Russia.
Also from the Daredevil series, we see an icon of (presumably) St Cyprian in the home of young Elektra Natchios (better known simply as Elektra) during a lengthy flashback sequence.
Hmm... being involved with the Black Widow AND Elektra. Matt Murdock (the Daredevil) must have a thing for Orthodox women =P
