Gravity (2013)

Corrected entry: When Ryan is in the Soyuz capsule, several items are seen inside the capsule. For example, sticky notes, pens, guides to using the capsule, fire extinguisher, etc. When Ryan discovers she needs to get rid of the parachute in order for the Soyuz capsule to leave, Ryan puts on a space suit, opens the airlock and removes the ropes connecting to the parachute. After the debris storm, Ryan returns to the Soyuz capsule and it can be noticed all of the items are still there inside the capsule. Wouldn't these items have been sucked into the vacuum of space when Ryan released the airlock earlier on? After all, there is nothing restraining them. (00:53:30)

Correction: No, because she could not just open the hatch without equalizing the pressure first. Other wise it would have been very dangerous and sucked her out, potentially damaging her suit in the process and having her lose control and be sucked out into space. Before opening the hatch, she had to either compress the air in the capsule back into the ship air storage, or have the air pumped out into space slowly to not affect the inside of the ship. Thus when she opens the hatch, the pressure was equal to zero, with no air to rush out, taking any items with it.

Actually yes, if the door was open air would rush out. Pressure being equal to zero doesn't create a wall, or barrier of any kind that keeps the air from rushing, and taking items with it.

If pressure is zero then there is no air that would rush out.
