The given limit problem is:

\[
\lim_{x \to 3} \left(-x^3 - 4x^2 + x - 3\right)
\]

To solve this, we can directly substitute \( x = 3 \) into the expression because it's a polynomial function, which is continuous everywhere.

Let’s substitute \( x = 3 \):

\[
- (3^3) - 4(3^2) + 3 - 3
\]

Simplifying:

\[
- 27 - 4(9) + 3 - 3 = -27 - 36 + 3 - 3
\]

\[
= -27 - 36 = -63
\]

Thus, the value of the limit is:

\[
\boxed{-63}
\]
