Colin Farrell

Behold! I have roughly outlined his thumb and 'measured' his peen using the thumb widths. I don't know the statistics but my thumb is 1.2" wide.

You see that he fits 5 thumbs on his dick with a bit left over. If we say the bit left over is 0.5" then his dick is 6.5" (1.2x5 = 6).

Girth looks to be around 5.5"-6".

You're welcome. Also the video is here:

EDIT: just realised I may be a bit out on the start of the thumbs so could be an extra half inch in there. Same with the bit at the top (could be 1" over). So my revised estimate is 6.5-7.5" in length.
I think your measurement is still a bit off. But your edited version seems to be a tad closer if we use your upper end of the range you mentioned.

Taking a shot from when his cock is at its highest point when he's holding it, and considering that a man's thumb (in general) is about 2.5cm wide or so, I was able to fit his thumb across his cock 8 times pretty much without any overlap or left over room at the end of his dick.

2.5cm x 8 = 20cm
20cm is quite a big dick, that's 7.8 inches.

You can also fit about 2 and a half of his thumbs across his girth.
So 2.5 + 2.5 + 1.25 = 6.25cm across, which is about 2.5 inches wide which is also quite a thick ass cock.

I think his bush and his height just makes his dick size look slightly less bigger than it actually seems to be, but yeah he seems pretty hung with an almost 8 inch long and an almost likely 6 inch thick uncut Irish cock.
