histrionic

Of or relating to actors or acting.

After three years of constant applause, Miss [Elizabeth] O'Neill directed her steps towards the summit of histrionick exertion, being engaged for the season of 1814 at Covent Garden, where she made her first entrée as Juliet, on the 6th of October, being at once recognised as the first Hibernian actress, who had joined transcendant beauty with rare histrionick talent, since the time of Mrs. [Peg] Woffington.

On Saturday, Miss F. H. Kelly played Belvidera for the first time, to a crowded House, and for her own benefit;—for her own benefit in every way, for the performance added a wreath to her histrionic laurels, and drew down the warmest testimonies of applause.

Excessively dramatic or emotional, especially with the intention to draw attention.

[F]oppiſh airs / And hiſtrionic mumm'ry, that let down / The pulpit to the level of the ſtage, / Drops from the lips a diſregarded thing.

[T]he mode and the expression of honour to literature in France has continued to this hour tainted with false and histrionic feeling, because originally it grew up from spurious roots, prospered unnaturally upon deep abuses in the system, and at this day (so far as it still lingers) memorialises the political bondage of the nation.
