“Somewhere Out There,” the maudlin theme song to the animated “An American Tail,” is audio torture.

It’s not just Linda Ronstadt and James Ingram’s warbling. It’s the heavy-handed longing – important to the song – that is betrayed by bogus lyrics like “And even though I know how very far apart we are, it helps to think we might be wishing on the same bright star.”

Patricia Riggen’s “Under the Same Moon” takes the song’s phony concept even further. It swipes the faux sentimentality of “Somewhere” and duct tapes it to our nation’s very real border-crossing dilemma. It pretends to address a serious issue but ends up degrading an entire race.

The sad sacks sleeping under Riggen’s moon are 9-year-old Carlos (Adrian Alonso) and his beloved mother, Rosario (Kate del Cast-illo). She’s an illegal immigrant cleaning houses in Los Angeles. He’s a virtual orphan caring for a sickly grandmother and fending off his greedy uncle. When granny kicks the bucket, Carlos finally sets out to cross the border and join Mom in the City of Angels.

The child’s obstacles amount to a string of poorly written, obvious clichés that litter the road many travel from Mexico City to the southern United States. Screenwriter Ligiah Villalobos peppers Carlos’ journey with broadly drawn, grotesque (and, of course, non-Mexican) villains. She recruits “Ugly Betty” star America Ferrera for a ham-fisted confrontation at a border checkpoint. Why is it people smuggling immigrants into our country always are told they can proceed, only to be stopped seconds before crossing safely for a broken taillight or expired registration?

“Moon” tells a glossy version of immigration, where surly (but kind-hearted) vaga-bonds shepherd scared child-ren to their mother’s waiting arms. “Moon” is so safe it’s dull, so predictable it’s toothless, and so corny it’s insulting.
