The director couldn't share much from his first day at work, but he still teased the 'cool scene' he shot.

Ron Howard celebrated his first day on the set of the Han Solo Star Wars project with a behind-the-scenes photo -- albeit one that didn't reveal a whole lot.

The Oscar-winning director
-- who was recently hired to finish production on the film -- commemorated the occasion with a snapshot of his feet, a case of water bottles and some electrical cables on the floor of the soundstage.

"Cool scene today," Howard captioned the pic. "But I'm afraid this is the most revealing image I dare share from my 1st day on the set of the Untitled Han Solo movie."

Production on every recent film in the Star Wars franchise has been notoriously shrouded in secrecy and non-disclosure agreements to prevent leaks and spoilers -- and given the concerning publicity surrounding this latest project, discretion is probably Howard's best bet.

The 63-year-old filmmaker is taking over the reins on the project after the film's original directors, Christopher Miller and Phil Lord, were fired from the project on June 20 -- after several months of filming -- following "creative differences" between the pair and Lucasfilm President Kathleen Kennedy.

After it was announced that Howard had been selected to helm the blockbuster, he took to Twitter to share his excitement, writing, "I'm beyond grateful to add my voice to the Star Wars Universe after being a fan since 5/25/77. I hope to honor the great work already done & help deliver on the promise of a Han Solo film."
