Black and White (2012)

Case in point: an extraordinary, largely improvised scene in which Downey, who shot his stint as a flamboyant bisexual before being imprisoned on drug-related charges, makes sexual advances toward Tyson.

Meanwhile, Shields, wearing colorful dreadlocks as Downey's documentarian wife, keeps her camera trained on the action.

''You'd think that Brooke would have run over to stop Mike,'' says Toback, ''but she kept right on filming with her own camcorder, which gave us the best footage of the scene we got.''
