David Oyelowo, Saoirse Ronan, and Sam Rockwell will soon be sharing the big screen together.

According to The Hollywood Reporter, actors David Oyelowo, Saoirse Ronan, and Sam Rockwell have all signed on to star in director Tom George’s upcoming murder mystery.

The untitled film hails from Searchilght Pictures and features a screenplay written by Mark Chappell whose recent credits include the Netflix original series, Flaked, as well as 2016’s The Rat Pack.

Set in 1950s London, the untitled murder mystery centers on a Hollywood film producer who’s attempting to take a popular West End play and turn it into a film. Things get a bit more complicated for the producer when members of the production start getting killed off one by one.

Rockwell is set to play Inspector Stoppard, who, together with Ronan’s overzealous rookie Constable Stalker, must figure out whodunit before it’s too late.

It’s not yet clear who Oyelowo will play in the untitled mystery, or how his character will fit into the fold of things.

Also unclear is when we can expect to see the mystery movie hit theaters. Even so, film fans won’t be left wanting for new material from the A listers who’ve just signed to star in the Searchlight production as all three have projects coming down the pipeline.

Coming up next for Ronan, fans can catch her next starring opposite Kate Winslet in the romance drama, Ammonite.

Meanwhile, Oyelowo can next be seen starring opposite Angelia Jolie in Come Away.

Finally, Rockwell currently stars in the Disney+ original movie, The One and Only Ivan where he lends his voice to the titular character.
