Robert Downey Jr. Pictures: Splice Los Angeles Premiere Red Carpet Photos and Pics

Robert Downey Jr. Pictures: Robert Downey Jr. arrives on the red carpet at the "Splice" movie premiere held at Grauman's Chinese Theatre on June 2, 2010 in Hollywood, California.

Clive and Elsa are a pair of brilliant scientists whose cutting-edge experiments in genetic engineering make them superstars in their field. As devoted to their careers as they are to one another, they start conducting unauthorized experiments with new animal species that show great promise. Drunk with their god-like powers, they introduce human DNA into one of their creations, producing a creature that is greater than the sum of its parts: a rapidly developing animal/human hybrid that may be a step up on the evolutionary ladder. While this female creature inspires maternal feelings in Elsa, she evokes something far-from-paternal in Clive, something that poses a threat to them all. Then, when this seemingly perfect organism makes a final, shocking metamorphosis, it is mankind itself that is threatened.

"Splice" opens in theaters nationwide on June 4.
