Thanks to Fritz for the following
Nothing major. But I HATE when TPTB do the ol' "reverse camera angle for no good reason" trick. 6.5 minutes into "The Shape Of Things To Come (S04E09)," when Ben appears in Tunisia, a vast mountain landscape is shown. In "The Life And Death Of Jeremy Bentham (S05E07)," ironically, about 6.5 minutes in, Locke appears in the same area of Tunisia. When shown the vast mountain landscape this time, however, the mountains are reversed.
