Dunno about that... it may be one rare thing the movies get right. Certainly landing and take-off are the difficult parts of flying, but the easy bits are mind-numbingly easy.
If you know how to land, most of the conversion becomes a matter knowing what the particular aircraft's stall speed is, gear down speed, flap angle, and so forth.
It was a nice clear day with not much wind. Find a nice big long runway with no crosswind, and I think getting the aircraft on the ground in one piece is very do-able. It wouldn't be a pleasant landing (much of airliner flying precision comes down to passenger comfort) but I think they'd be okay.
The key thing is, if he's a pilot, he understand the concept of stall and flap and approach angle and all of that stuff, which means Approach can talk to him in technical terms, not layman's terms.
Bear in mind, before instrument landing systems were developed the ground-controlled approach or "talk-down" was standard practise in situations in which a visual approach was impossible.
And it really wouldn't surprise me if a similar scenario - an amateur or non-pilot landing an aircraft with the aid of ground controllers - has occured multiple times in the history of aviation.
