Not sure I could call it favorite but most watched for me used to be The Guns of Navarone which I watched endlessly as a kid. I lost count after 11 viewings but I suspect that Das Boot may have now overtaken it. Brilliant film, even if originally a made for TV mini series.
Honorable mentions also go to Dirty Harry, Scarface, the Godfather series and anything with Errol Flynn in it (especially on a Sunday afternoon)!!
