theater, cinema, acting

You were getting ready for another rehearsal, when suddenly two guys entered the room, and our boss, Mikhail Valentinovich (a pretty good person, but frivolous), announced:
-These two guys work with us. Our theater is big, there are a lot of roles, we can't handle it ourselves.
You were all taken aback. Mikhalya (that's what you call him to the entire cast when he's not in his office) introduced them:
-This is Roman.
He pointed to a nice-looking blond guy with brown eyes, quite a good shape, and of average height. There was something attractive about him.
-and this is Alexander.
Mikhail pointed to the guy. He was even more handsome than the first. His chestnut hair literally shone, and his hazel eyes sparkled with kindness. He smiled sweetly, even shyly, if you can call it that. The guys were dressed in classic clothes: trousers, a T-shirt, sneakers. Nothing out of the ordinary. But there was a connection between them. They were best friends. You could tell by their poses and glances. Artem (your makeup artist) greeted the new actors as usual. He showed Sasha and Roma around the place, including his work location. Sasha and Roma nodded politely, keeping up the conversation. They were introduced to your cast.
Dasha (actress, sweet, kind, 19 years old)
Artem (make-up artist. Good, kind. 20 years old.
Zhenya (girl, actress, 19 years old)
Maria (actress, beautiful, smart, kind, 20 years old)
Gleb (actor, costume designer, kind, always ready to help, 21 years old)
Diana (understudy, kind, cheerful, 19 years old)
Vitya (understudy, kind, cheerful, 20 years old)
Mikhail Valentinovich (Mikhalya, the theater's chief director. Cheerful, kind. 39 years old)
Lavender Alekseevna (Lavender, that's what you call her, she allows it. She's your mentor, sweet, kind, on the same wavelength with you. 37 years old)
You greeted the new actors with a few polite words like "we're happy to work with you" or "we'll get along!"
Next week you have a performance. Everyone knows the lines, including the newcomers. But you don't know the roles yet. Learn everything for everyone, just in case.
(Don't forget to describe yourself, you've been working in the theater since you were 18, and you're all friends with the guys.)
