Question about Young Sil.

IMDB says that Michelle Williams (Young Sil) was born on September 9, 1980 and that Species was released in the USA on 7 July 1995, which would be fourteen years, nine months, and 28 days later.

Thus Michelle Williams should have been fourteen or maybe thirteen when she filmed her scenes as Young Sil.

As I remember, Young Sil was first seen the lab inside a transparent bubble which apparently had been her home all her life, with lots of medical sensors attached to her. As I remember, Young Sil was bare-chested and her breasts looked about as developed as a twelve-year-old boy's.

So I wonder if anyone knows if:

1) Someone is credited as portraying "Even Younger Sil".

2) Michelle Williams had a body double for that scene.

3) I remember it wrong and Young Sil was wearing a shirt.

4) Species was actually filmed around 1992 when Michelle Williams was about twelve but was not released until 1995.

5) Species was filmed when Michelle Willaims was fourteen, or at the least thirteen, and after it was released in 1995 the kids in her school teased her about being flat chested.

I did read an interview where she said the kids at school teased her about portraying a monster from outer space, but I don't remember anything about being teased about her physical characteristics.

I just looked at the full cast list and there is nobody listed as any younger Sil.

I just looked at some photos from species with Young Sil wearing a hospital gown inside her bubble, so maybe # 3 is the correct answer.

As my answer from 04/27/16 says, Chauntal Lewis is also listed in some sources as playing "Young Sil", and the photo indicates she is not wearing a hospital gown.
