Trying to find the actual credits of Miguel A. Nunez, Jr. and the CLT has quite a mixed bag of results. 11 total variations of credits. The most prevailing credit is the form with diacriticals that may not be in the film credits, and not surprisingly is the IMDB form. I only have Lethal Weapon 3, so please help me out with this name. Thanks in advance.

I have indicated where the name variant appears in at least 1 profile as credited as data, and I have tried to count the various titles(profiles) for the films listed. Pluto Nash and The Adventures of Pluto Nash are probably the same credits, but I really don't know.
Titles in orange are titles with existing credited as data, and in the case of Street Fighter and Lois & Clark, both have 2 different credited as entries.
Titles in purple are those that have credits under more than 1 variant, but no credited as in CLT.
Red titles are verified incorrect, Bold Green are verified correct.

Jumpin' Jack Flash: Miguel A. Nunez, Jr.
Harlem Nights: Miguel Nunez

His appearance in 'Dr. Dolittle 2' is indeed a deleted scene only, for which he isn't credited in the regular film credits. So that one shouldn't be taken into consideration.

As a rule of thumb, I'm very wary of accents in common names: I've found that about 75% of the film credits out there tend to drop them, meaning that DVD Profiler common names will mostly be accent-less. There will, of course, be exceptions, but generally I've found that if you find lots of different accented credits for someone in the CLT, it's a sure-fire sign of IMDb-data.

I know I have mistakes in counting titles/profiles for Miguel A. Núñez Jr. because my total is 118(230) instead of 107(228). All of the other variants add up correctly, so I'll try to find and correct my counts. I don't believe it will make a significant difference, but I have the afternoon off.

Thanks T!M, you get another greenie. Now I have only 2 left for today.

Look at that, with only 7 films verified, the adjusted total has now swung to Miguel A. Nunez, Jr. 75(141) as the leader for the most credited form. Imagine that.

Quoting Giga Wizard:

I see T!M posts the Leading credits, please allso verify the cast credits itself

Rest assured that I did NOT go by "leading credits" - my findings were taken from the "standard" cast list in the end credits. 'Lois & Clark' is a bit of an exception, since it lists the "big guest stars" in the opening credits, and the smaller roles in the end credits. No names are repeated, so our guy only appears in the opening credits for that one.

In the meantime, I've been able to confirm one more credit: he's credited as Miguel A. Nunez, Jr. in 'Pluto Nash'. That really seems to be the common name.

Well, going through it a couple more times, I now have the totals addiing up to 108/228 so I am only of by 1 title count and I give up trying to get it closer. I made the adjustments to my spreadsheet, so the post reflects corrected adjusted results. 

If anyone could jump in with Friday the 13th 5: A New Begining, The Nutty Professor II: The Klumps, Street Fighter and Return of the Living Dead, it would be greatly apprecieated.

Friday the 13th 5: A New Beginning he's actually credited two different ways.

Directly after the film ends, there's part of a cast listing under the banner "Featuring". There, he's credited as Miguel A. Nunez Jr.

When you get further into the credits, the film actually lists all the credits in alphabetical order (which I guess we would qualify as the film's end credits from which we're actually supposed to pull the cast from), and there, here's credited as Miguel A. Nunez, Jr.

I verified this onscreen using the version of Friday the 13th - Part V: A New Beginning that's included in the Ultimate Edition DVD Collection Boxset. Disc ID: 97AC2D5599053DBB [FRIDAY_THE_13TH_D3]

Hope that helps!

Sorry for coming in so late... just checked Street Fighter: The Ultimate Battle, and he's credited as MIGUEL A. NUNEZ, JR. in both the opening and end credits.
