Back in March, we showed you a glimpse of the giant, man-eating hair Jennifer Lawrence was sporting on the set of her then-unnamed new movie.

Now we have the first trailer from what's since been titled 'American Hustle,' which again teams her with her 'Silver Linings Playbook' director David O. Russell and co-star Bradley Cooper. And it looks like it was worth the wait.

'American Hustle' is a fictionalized account of the infamous Abscam operation of the late '70s and early '80s, during which a rebel FBI agent and two con artists worked together to reveal high-level political corruption.

But even if you don't know anything about Abscam, just looking at the clothes and hair worn by Lawrence, Cooper and Amy Adams should make it pretty clear when the whole thing happened. Because holy Aqua Net, Batman.

There isn't a lot of dialogue in the clip, but visual highlights include Lawrence and Adams in skimpy underthings, Cooper giving himself a man-perm, and (speaking of Batman) a barely-recognizable Christian Bale spanking a woman on his desk. As you do.

'American Hustle' opens this Christmas -- just under the wire for award season.
