Terrible casting
Good film but would have been MUCH better with good casting for the sons.
At time of filming they were 31 and 25 - and pretty much looked and acted those ages.
Actual dialogue, script and 'action' said they should have been 18 or at least acted and looked that age. Grown men sitting in a tub together mutually washing their hair - OMG. (Gotta say even 18 would have been a stretch for that particular scene).
