VIDEO: LeBron's appearance in 'Trainwreck' trailer is pretty strong

When it was revealed in May that LeBron James would make an appearance in the Judd Apatow vehicle "Trainwreck," the assumption was that his cameo - one of many big-name cameos announced - would be relatively small.

The first trailer for the movie, which stars comedian Amy Schumer and former Saturday Night Live stalwart Bill Hader, suggests James may have a more significant role. Hader plays a sports doctor, and James - playing himself - is Hader's marquee patient.

That includes, according to a scene in the trailer, being Hader's romantic confidant and viewing partner for "Downton Abbey."

Have a look:

The cast features an unbelievable collection of funny people, so there's a good chance James has his face all over a summer hit. The movie is due out in the U.S. on July 17.
