Let's simplify the expression step by step:

The given expression is:
\[
(-27) \times 1011 - 27 \times (-12) + 27 \times (-1) \times (-27) \times 1011 - 27 \times (-12) + 27 \times (-1)
\]

First, let's organize it:
1. \( (-27) \times 1011 \)
2. \( -27 \times (-12) \)
3. \( 27 \times (-1) \times (-27) \times 1011 \)
4. \( -27 \times (-12) \) (again)
5. \( 27 \times (-1) \)

Now we'll calculate each piece.

1. **Calculating \( (-27) \times 1011 \)**:
\[
-27 \times 1011 = -27297
\]

2. **Calculating \( -27 \times (-12) \)**:
\[
-27 \times -12 = 324
\]

3. **Calculating \( 27 \times (-1) \times (-27) \times 1011 \)** (note that \(-1\) and another \(-27\) will cancel):
\[
27 \times (-1) \times (-27) \times 1011 = 27 \times 27 \times 1011 = 729 \times 1011
\]
Calculate \( 729 \times 1011 \):
\[
729 \times 1011 = 736239
\]

4. **Calculating \( 27 \times (-1) \)**:
\[
27 \times -1 = -27
\]

Now substitute these calculated values back into the expression:
\[
-27297 + 324 + 736239 + 324 - 27
\]

Now, combine the values step-by-step:
1. Start with \( -27297 + 324 \):
\[
-27297 + 324 = -26973
\]

2. Then add \( 736239 \):
\[
-26973 + 736239 = 709266
\]

3. Then add \( 324 \):
\[
709266 + 324 = 709590
\]

4. Finally, subtract \( 27 \):
\[
709590 - 27 = 709563
\]

Thus, the final result of the expression is:
\[
\boxed{709563}
\]
