Filming for the "Transformers: Age of Extinction" sequel has been anything but easy for director Michael Bay.

In the past two weeks, the fourth installment of the film has undergone not one, but two extortion attempts by Triad gang members. In addition, Bay himself was attacked on set.

The film stars Mark Wahlberg, Nicole Peltz, Kelsey Grammer, and Stanley Tucci.

Since then, Peltz, who plays Wahlberg's daughter in the sequel, says filming on "Age of Extinction" wrapped October 27 .

Through all the turmoil, h ere's a look at what Bay and the crew have been filming in HK:
