    TV shows and movies frequently cast adults in teenage roles — one reason is that actors 18 and over can work longer onset hours, as opposed to minors. Most of the time, these actors are in their 20s, but some play teenagers well into their 30s and beyond. In some cases, older actors playing teens is part of the project's schtick.

    Here are 13 actors who were 30-plus years old when they played teenagers:

    1. Nicola Coughlan was 31 when she began playing 15-year-old Clare Devlin on Derry Girls.
