Learning to cry.

As an actor/actress, your duty is to have an expanded imagination. Develope your imagination, and you have enhanced acting skills (making you more apt for auditions than others). Imagine the situation, assuming it's already depressing, ten times worse. Two other people are assasinated, your son has a day to live rather than a week, your father dies in Iraq rather than simply being deployed. Acting means convincing yourself that you're in that position. Try writing out different, more dramatic takes in the scene, then practice by placing yourself in that position, and keep it up till you get the hang of it. It's all techinally 50% imagination and 50% determination in the realm of acting. Hope that helps :]

Oh my gosh im the exact same way! I had to play the nurse in romeo and juliet last year and couldnt get myself to cry for the life of me! :( Its very frustrating, i know the way that you feel!

I don't cry easily. Sometimes bright lights make my ears tear up (rarely thought) but that's it.
I've never actually had to cry, but my advice is to think of humanity catastrophes. Exagerate the situation. You're getting dumped, your mom is kicking you out of your house (example). If ntohing works, cover your eyes and sob (its not the best solution thought)(make sure this is okay with your director BEFORE)

Well i ususally think of comething really sad, but someone the Hollywood actors put drops in thier eyes before a scene where they have to cry. Or you can think of the situation your character is in and TA DA!!! TEARS! Well..thats what i do.. hope i was of some help :]

Whether or not you need legitimate tears depends on the kind of acting you're setting out to do. If you want to be a stage actor, getting real tears isn't quite as important as conveying the emotion that you're trying to get across. You want to focus more on accurately representing that emotion than trying to actually cry. You don't want the performance to suffer because you weren't focused on the real acting. If you want to to screen acting though, you'd probably want real tears for that. I can't really give you very good advice on producing tears at will (I can't really do it myself) but what I can tell you is just do your best to really feel what the character is feeling and deliver the lines and the actions with the appropriate emotion... hopefully the tears will come on their own that way!

I had this same proublem for a play.I was so bad at first. but then i just let my self free.and i could cry.

im a voice actress and a normal actress crying I usually just practice in a mirror and do a few little sounds.

What I do is think of death, of my favorite celebrities who died, and I listen to, or play in my head sad songs. Some ones that make me cry are No-One But You by Queen, Just A Dream by Carrie Underwood and Hey Jude by The Beatles.
Also, you can think of why your character cries in the play. Step into your characters shoes, pretend you are your character and all this is happening to you.
After the performance, listen to happy music so you feel better!
