Box Office Guru with the details:

Robots ruled the box office as the highly-anticipated action sequel Transformers: Revenge of the Fallen generated the second biggest opening in history with a gargantuan $201.2M in its first five days, according to studio estimates, sending the overall marketplace to its highest gross of the year. The eye-popping figure included $112M over the traditional Friday-to-Sunday period plus an additional $89.2M since its Wednesday launch. Playing ultrawide in 4,234 theaters including 169 IMAX screens, the Paramount release averaged a stunning $26,453 over the Friday-to-Sunday period and a gigantic $47,531 over five days.

The only other film to ever gross more in its first five days was last summer's The Dark Knight which hauled in a slightly better $203.8M from 4,366 venues. The first Transformers bowed to $155.4M in 6.5 days and needed 12.5 days to break the double-century mark on its way to a $319.2M finish.

The Michael Bay-directed pic set a number of other box office milestones. It set new records for a June opener, beating the $93.7M of 2004's Harry Potter and the Prisoner of Azkaban, and for a live-action film from Paramount exceeding the $100.1M of last summer's Indiana Jones and the Kingdom of the Crystal Skull.

This continues 2009's hot streak (why spend money on a vacation when you can see a terrible movie about robots?)
