Having been pictured getting close to her director and co-star between takes, Sienna Miller was unsurprisingly flying solo on Thursday.

The actress, 33, cut a glum figure as she arrived to film scenes for Live By Night, three days after being pictured holding hands with Ben Affleck, 43.

She was evidently off-duty, thanks to her Snoopy leggings and slouchy jumper, which served as a contrast to her regular 1920s costume for the Prohibition Era crime drama.

She returned to her quirky, individual style, which featured chipped black nail polish and loose untamed curls, while breaking for a cigarette.

Her counterpart was similarly dressed down and obviously not filming his own scenes as he arrived in a car by himself.

Ben and Sienna play Joe Coughlin and Emma Gould, a couple who've been known to share kissing scenes on set.

But the acting pair were mysteriously not filming when they were captured linking hands outside their trailers earlier this week.

Sienna was in full costume, while Ben was clearly in directorial mode for the day as he dressed comfortably in a woolly hat and thick knit. 

The film, co-starring Scott Eastwood, Elle Fanning and Zoe Saldana, is based around a group of individuals and their dealings in the world of organized crime.

Sienna and Ben are both thought to be single following their own respective splits in 2015 from fellow actors.

American Sniper star Sienna is said to have called off her engagement to Tom Sturridge, with whom she has daughter Marlowe, in July after four years.

Meanwhile, Ben's relationship woes have been well-documented after they announced that he and Jennifer Garner, the mother of his three children, would be getting a divorce July, following their 10th wedding anniversary.
