Sandra Bullock is now officially the frontrunner for Best Actress after copping SAG’s award in the category. She not only give a wonderfully self-deprecating acceptance speech, she did beautiful presentation to Betty White, who received a career achievement award. Bullock, at 45 — an age when most actresses are relegated to supporting roles — became the first member of her sex to topline a movie that grossed over $200 million, “The Blind Side.” Bullock got that part after it was turned down by Julia Roberts, who also nixed “The Proposal” — a $165M hit for Bullock.
