[2] She did occasionally play comedy as well, and one of her most acclaimed roles was as Mrs Dorsan in Den svartsjuka hustrun ('Jealous Wife') by Desforges.

During the regency government years of Gustav IV Adolf (1792–96), she had risen to become one of the most valuable members of the Royal Dramatic Theatre, which is illustrated by the fact that her income from the theater belonged to the elite of the actresses there.

Maria Franck had, in parallel with her acting career, given lessons in declamation, and in 1819, the year following her retirement from the stage, she was engaged as the principal of the Royal Dramatic Training Academy, a position she kept until 1823.

In contrast to most actors of her generation, which often had financial problems, Maria Franck was reportedly well off during her retirement, although this may have been in part because of her husband, who was a successful engraver.

Among her parts were "One of the pleasures" in Armide by Gluck (season 1786–87), Maria in Gustaf Adolf och Ebba Brahe (Gustaf Adolf and Ebba Brahe) by Gustav III (1787–88), Flattery in Alcides inträde i världen (The arrival of Alcide in to the world) by Haeffner (1793–94), Theodora in De gamla friarna (The old suitors) by Dalayrac (1795–96), Antiope in Renaud by Haeffner (1800–01), Sabina in Den förmente prinsen (The supposed Prince) (1807–08), Madame de Veronne in Ambroise (1812–13), Gertrud in Den Schweiziska familjen (The Swiss family) (1815–16) and the abbess in Nunnorna (The nuns).
