This must be one of the very few films to have been drawn entirely from a single sight gag - in this case, the title "Twins" matched with the visual contrast of Schwarzenegger with DeVito. I find it difficult to imagine someone writing this and then thinking "Now who shall we cast?" - it seems much more likely that it was a project developed with one or both of these performers in mind.
And from a slight beginning, it turned out very well. The sight gag never fails to please, the character similarities and contrasts work very well, the brothers' quest is an adequate plot, the female leads both work well (and Kelly Preston is always sufficient to bring a dead man back to life), and DeVito's character has a nice development arc, as they say: ultimately, the story is about Julius redeeming Vincent.
The sentiment feels real and is never overdone.
Oh yes, and it's funny, too.
