Since graduating from the National Theatre School of Canada in 2008, Mani Soleymanlou has been very active on the Montreal theatrical scene. He has participated in several remarkable theatrical productions such as: Projet Andromaque (Serge Denoncourt), l'Opéra de Quat'sous (Brigitte Haentjens) and Les trois mousquetaires (Serge Denoncourt). 

In 2011, Mani founded Orange Noyée, a theatre company within which he writes, directs, and performs. He creates the triptych: UN, DEUX, and TROIS. After Montréal, the trilogy is staged in Paris with 40 performers. Mani then creates a new cycle with Ils étaient quatre, Cinq à set, Huit and Neuf (Titre provisoire). He concludes with his solo ZÉRO. He then presents a new version : Un. Deux. Trois with 36 performers, during the 2022 season of the Jean Duceppe Theatre as well as on tour across Canada for several months.

On television, we have seen him in series such as O', Marche à l'ombre, Lâcher Prise, as well as La Faille, C’est comme ça que je t’aime, Épidémie and M'entends-tu. We can also see him in the feature films À tous ceux qui ne me lisent pas by Yan Giroux and La femme de mon frère, directed by Monia Chokri. In addition, he is part of the cast of Malek by Guy Edoin and the youth movie Mlle Bottine. 

Still on the small screen, we see him in Virage and Survivre à ses enfants. Since 2022, Mani has played one of the main roles in Avant le crash, the Radio-Canada series written by Éric Bruneau and Kim Lévesque-Lizotte. He also plays Victor in the grim series In Memoriam.

His 2023 is also marked by theatre. He directs the play Mille at the Quat'sous and returned to the stage of the Théâtre du Nouveau Monde where he formed the electrifying duo of Laurel and Hardy with Luc Bourgeois in Abraham Lincoln va au théâtre, directed by Catherine Vidal. Since 2021, Mani has also been artistic director of the French Theatre at the National Arts Center in Ottawa.
