Grey's Anatomy (2005) - 7 major mistakes

Continuity: When Chief Webber is sitting alone in the dark his watch says 6:30, seconds later Dr. Bailey comes in and tells him that Denny Duquette died at 7:42 that evening.

Continuity: Viper has a green headband on with a white bandage underneath. But as he leaves, then kisses Meredith, the bandage has vanished.

Continuity: We see a nurse writing down "Yang, C" on the assignments board; note the handwriting. Later, when Burke notices that Christina's name is on the board, the handwriting of "Yang, C" is completely different and other minor writing differences are noticeable too.

Continuity: When Izzy, George and Christina walk over to the vendor, talking about Dr. Sheppard and Meredith, Izzy is in the middle, eating snacks from a packet. Between shots she alternates from holding the pack either up or down.

Visible crew/equipment: When they arrive at work near the beginning, as Meredith exits the car, and walks past, the boom mike is reflected in the car, in front of her, following her along.

Continuity: Izzie's glasses disappear from her face, when the interns are getting the gurney from the airpad.

Continuity: Olivia walks into an elevator with Izzy already inside and they go up 3 floors. When Izzy leaves the elevator, it's the same floor from which Olivia came (same equipment and decor).
