Jennifer Aniston’s husbands are set for an awkward showdown — both her ex Brad Pitt and current hubby, Justin Theroux, have movies coming out on Oct. 7.

The Pitt-narrated IMAX film “Voyage of Time” will go head-to-head with Theroux’s thriller, “The Girl on the Train.”

May the best Aniston man win.

It’s going to be a tough box-office battle to predict: Although Pitt’s the sixth-most-bankable man in Hollywood, his flick is a doc about the history of time, while Theroux’s is one of the most anticipated films of the year.
