I would go with Olive-sided Flycatcher over Eastern Wood-Pewee.
This bird seems to lack any prominent wing bars that an Eastern Wood-Pewee should display, as said earlier by Canoncan. Also, the vested appearance of this bird seems too strong for an Eastern Wood-Pewee. There is also some streaking shown under the wing on the flight shot, a wood-pewee should show a smooth grey side to the belly. Finally, the bill seems too thick and bulky for a wood-pewee.
Hope this helps,
