agieren vs spielen
to play
'spielen' and 'agieren' can both have to do with acting. When someone portrays a role in a film or play, you can say that the person 'eine Rolle spielt' (plays a role) or 'auf der Bühne agiert' (acts on stage). 'spielen' is the normal, simple word for this. 'agieren' often sounds more formal and tends to emphasize how someone acts or performs. Outside theater and film, 'agieren' usually means 'to act' or 'to behave in a situation', not 'to play a game'. That is why the words can be confused if you only think of 'Rolle' (role) or 'Schauspiel' (acting).
agieren
Auf der Bühne agiert der junge Schauspieler sehr ruhig und sicher.
On stage, the young actor performs very calmly and confidently.
