Titanic turns 20 this year, and its birthday is bringing what will no doubt be an endless stream of cast reunions and references to the ship that sank but launched a thousand careers in the process. Take what happened Wednesday night at the annual auction hosted by the Leonardo DiCaprio Foundation in St. Tropez, France. Kate Winslet and Billy Zane joined DiCaprio at the event, which raised more than $30 million for the foundation dedicated to fighting climate change. A photo op ensued:

“Gang’s back together. Now we’re saving icebergs. Go figure . . .” Zane wrote in a cheeky Instagram post. Then, he apparently slapped a serious filter on that image. But if you look closely, the image really does feature all three Titanic cast members smiling widely at the camera.

Though this year might be more special for Titanic than most, Zane has never hesitated to play the Titanic nostalgia card. In recent years, Zane has given multiple interviews about his opinion on Rose’s romantic choice and what happens when he hears “My Heart Will Go On” in a public place.

Winslet and DiCaprio have their own special connection to the film, namely a friendship that has led to Internet-breaking awards show reunions and even DiCaprio walking Winslet down the aisle at her 2012 wedding to Ned Rocknroll. The two have agreed to re-unite once again, and this time with a lucky bidder in tow; a dinner with DiCaprio and Winslet was put up for auction at the event. The winner of that dinner should certainly be excited for this meal, but they should be aware that Billy Zane may also be there with his camera—and his Instagram filters. And maybe his manservant Lovejoy, for good measure.
