Of course, all of the costumes were based on previous Hanks roles ... including that soldier who looked an awful lot like Matt Damon.

Yes, the whole thing was, as promised, “spook-tacular” and also — given the involvement of both Hanks and Damon — pretty delightful. It also marks the first and last time you may hear children happily chanting “Larry Crowne! Larry Crowne!”

Even Stephen Colbert himself was smitten by the Hanks charm, as noted in this tweet:

Exactly how nice is @tomhanks? Let’s just say when a person does something nice for you, there’s a reason you say T.Hanks.
