Movie Acting - More Things

I sometimes feel a sense of wanting others to get famous.  I think we need to consider ourselves to infiltrate into becoming movie stars so people can start getting selected for big roles.  I already put my stake on being the Wicked Witch of the West in The Wizard of Oz.  Now, that's not so much to ask.  I mean, think, a high quality actress willing to play a secondary role.  Who'd appreciate it more???
