10 Great Movie Duos Who Reunited And Made Garbage

9. Jon Favreau & Vince Vaughn

The Good: Swingers

The Bad: Couples Retreat

Long before Jon Favreau was a beloved director and Vince Vaughn was generating column inches as one of the more notorious leading men in Hollywood, Swingers put them firmly on the map, as well as director Doug Liman. The real-life friends took Favreau's excellent, funny script (including some roles specifically written for other friends) and turned it into one of the coolest comedies of the 90s. And it all hinged on their chemistry together, which has sort of like a proto-Fight Club bromance vibe about it.

Both are great in their roles too, which is more than can be said of the results of their reunion in 2009's turgid Couple's Retreat. Stunningly, it was written by Favreau (as well as Vaughn this time), but it fundamentally misses all of the beats that made Swingers so great. And the switch of Favreau from loveable loser to arrogant womaniser is just awfully misguided.
