Escape from Los Santos - S2-E11
Continuity mistake: During his second transformation, David tears his white shirt. When the Hulk is pulling Holly out of the cliff, the white shirt is nowhere to be seen. But when he takes her in his arms, he is wearing the torn white shirt.
Chosen answer: Bruce has always been the character's middle name. In the comics he is Robert Bruce Banner, here he is David Bruce Banner. Apparently the executives behind the show preferred the name David.
