Planetarium (released in the UK as The Summoning) is a French-Belgian drama film directed by Rebecca Zlotowski.

The film team conceives of a conventional script in which Laura plays a medium who channels the spirit of a widower's wife and the three become locked in a love triangle with the widower unsure if he is falling in love with his former wife or the medium.

The director walks off the film and blames the money Korben has wasted chasing ghosts as an excuse.

Laura runs into Eva, an actress she once knew, who helps her get a part in a film working with her former director.

No longer involved with spiritualism or Korben, Laura's film career in Nazi era France is assured.

The website's consensus reads: "The Summoning (Planetarium) looks out on a constellation of potentially brilliant ideas, but proves fatally unable to find its focus".

[11] Owen Gleiberman of Variety gave the film a negative review and wrote: "Planetarium is an inert and slipshod movie — messy and aimless, a period tale told with zero period atmosphere (you have to keep reminding yourself that it’s not taking place in 2016), built around a situation with enough possibilities to make you wish that the director, Rebecca Zlotowski, had taken advantage of at least one of them".
