Actor Shia LaBeouf, known for three “Transformers” movies and the last installment of the “Indiana Jones” franchise, has twice tweeted GPS coordinates from remote locations in Boulder County since Monday.

On Monday, LaBeouf, 29, tweeted from a road near the National Oceanic and Atmospheric Administration’s mountain test facility north of Boulder.

Earlier today, LaBeouf sent out coordinates to an unmarked road near Owl Creek Drive west of Boulder.

He tweeted at exactly noon Monday and Tuesday.

LaBeouf has not explained why he is sending the tweets or responded to a request for comment.

He is expected to appear at the Boulder Museum of Contemporary Art as part of a panel discussion with artists Nastja Säde Rönkkö and Luke Turner on May 22 as part of the MediaLive festival.

Festival director Nicole Dial-Kay said corruption is the theme of this year’s festival, and the three artists — who have formed a collective — have been invited to participate and offer their thoughts on corruption.

She would not say if the tweets had anything to do with the festival.

“We have no comment on that,” Dial-Kay said.
