As far as Jennifer Lawrence-related tie-ins go, this Carl's Jr./Hardee's commercial is about ten times worse than that time Subway created a special sandwich for Catching Fire, that movie about starving kids. (The video has been taken down; I guess Subway got embarrassed.) The Subway commercial was mostly just insensitive and weird. This commercial, in which a (non-Lawrence or Rebecca Romjin) Mystique has to transform into a dude before she can eat a Thickburger, manages to be insensitive, weird, and actively offensive.
Also making the rounds: A commercial that implies the reason sexist, catcalling construction workers are sexist catcallers is that they haven't eaten their daily Snickers. You can find that one behind the cut.
