1080p24 = 1080 x 1920 x 24 = 49,766,400 total pixels per second.
1080i60 = 1080 x 1920 x 60 / 2 = 62,208,000 total pixels per second.
1081p60 = 1080 x 1920 x 60 = 124,416,000 total pixels per second.

24 and 60 refer to the number of fields per second. In interlaced (i) a field only contains half of the picture (thats why I divided by 2 in the second example).

Commercial motion pictures are filmed at 24 frames per second. When converted to digital (video), anything greater than 24 fps is redundant storage of information.

1080p24 should actually take less storage space than 1080i60. Of course with digital compression such as MPEG-2, the numbers I'm giving are not representative of the actual data storage required for a movie. Actual storage required would be much less.
