Yeay! Now the 5D II is capable of manual exposure control in video mode. Previously, this was not possible as the camera takes full control of the exposure levels. The latest firmware 1.1.0 by Canon now allows you to control aperture, shutter speed and ISO! Well done Canon for listening to your customers! 
Copied from the Canon website:
Firmware Version 1.1.0 incorporates the following improvements and fixes.
- 1. Includes a function to enable the manual exposure setting when shooting movies.
- 2. Disables the function of the depth-of-field preview button when images are played back or when the menu screen is displayed on the LCD panel.
- 3. Fixes a phenomenon where the peripheral illumination of images cannot be properly corrected, even if the images were captured with the lens peripheral illumination correction function set to Enable.
- 4. Fixes the algorithms of the Auto Lighting Optimizer function when Custom Function C.Fn II-3 Highlight tone priority is enabled.
- 5. Fixes incorrect indications on the Arabic, Romanian, Spanish, and Ukrainian menu screens.
- 6. Changes the battery information displayed on the camera when using the optional Battery Grip BG-E6.
