Sam Worthington helped kick start Man on a Ledge into production when he expressed early interest in the script.

The sign on the roof of Englander's: "24 HOUR ROOF REPAIR". This is the reason for the massive blue tarp. Coincidentally or not, it provided additional coverage for Joey Cassidy (Jamie Bell) and Angie (Genesis Rodriguez).
The architectural building model used in the scenes with Ed Harris (beginning around 47:34), in which Harris' character, David Englander, shares his real estate development plans of the "Monarch Spire" to a group of investors, also appears in White Collar: Brass Tacks (2013). In that episode, Matt Bomer's character, Neal Caffrey pitches a slightly modified version of this same skyscraper model as "The Edwards City Tower" to real estate tycoon, Cole Edwards. (scenes starting around 18:54)
Released one year after "The Ledge", starring Charlie Hunnam. While both movies share the same Macguffin, the plots are vastly different, with Hunnam's film revolving around a scorned lover that must make a choice to save his own life, or his girlfriend's.
