Actors, who to me, look and act very much alike

It is probably just me, but there are two pairs of actors who I used to get mixed-up and even now that I know they are different, I still think are pretty similar.

What would be great is if they could be cast all in one movie. So here is the outline... Joey Lauren Adams (Chasing Amy) is married to Crispin Glover (Back to the future) and their bosses are their lookalikes: Crispin's boss is played by Renée Zellweger while Ms. Adams' is played by Matthew Modine (Full Metal Jacket & Married to the mob)

Twins, or more commonly, an actor playing duel roles has been done to death. Here, we have similar looking and sounding actors all playing in the same film. The makeup and costume people can make the actors look either more alike or less so, depending on what is needed as part of the story ark.

The plot gets moving when the couple decides to kill three birds with one stone: Invite over the boss for dinner--both of them (who are single) and set them up on a blind date as well. The dinner has lots of dramatic and comedic potential since each half of the married couple can talk shop with their respective boss, plus have inside jokes with each other. The only people left-out are the bosses, but only with respect to each other. Naturally they begin to date and to confide in their subordinate about how things are going. As they date, there is plenty of opportunity for the subordinate to take their boss's side in disputes or the opposite given their knowledge of the bosses personality and for fights and arguments to break-out between the married couple. The script almost writes itself.

The four lead parts do not notice that there is any similarity between them, but there should be 2-6 supporting cast who do notice and enjoy making smart comments about it throughout the film.
